    Integrated Industrial Edge Compute

    Predicting the future of new technology is often like gambling. Predicting the future of a massive locomotive on a railway track is quite predictable. The future of edge compute is more like a locomotive with a predictable future. It is already impacting the energy and mining industry today and there’s much more to come in the next few years.

    Let’s start with some general enterprise market numbers for context. In early 2023 Grand View Research identified that the edge compute market had grown from $1.9B in 2020 to $11.24B in 2022. Their research predicts an exponential growth curve that will continue at 37.9% compounded annual growth rate and reach $155.9B in 2030. That’s a very big number, almost 100X increase in 10 years. It’s safe to say this technology will touch almost every enterprise.

    Integrated Industrial Edge Compute
    Market Growth Projection

    Industry Trends


    These edge compute numbers may explain my boldness, but the business value of specific outcomes are what drives this growth in energy and mining. The following trends are what provide fuel for this growth in the near term.

    Digital Instrumentation

    I’m often reminded that digital instrumentation has been around for dozens of years in process control. In spite of our history with digital instrumentation, a surprising number of instruments are still read manually and entered by hand into computer systems. This is changing. The use of centralized operations centers and remote experts raises the need for visibility across all process elements from remote tools and dashboards. The move to more complete digital instrumentation is making the role of compute and data infrastructure critical to operations.

    Cloud Challenges

    Almost everyone has drastically shrunk their corporate data center footprint and moved their compute functions to the cloud. This approach continues to be problematic for many operational environments that struggle to get reliable connectivity. Even with the improvement of today’s connectivity options, the risk of failure is still too high for critical operations. In addition to the reliability risk, the latency risk for certain operations is also too high for cloud services. These two factors make compute at the edge an important consideration.

    Artificial Intelligence

    In 2023, It seems like every conversation or publication must contain a reference to Artificial Intelligence (AI) and for good reason. AI can cut through the noise and focus our attention on the critical data points that affect meaningful business outcomes. In many cases the resulting algorithms are quite simple and can be deployed in lightweight container apps at the edge.

    Container Apps at the Cisco Edge


    AI is one of multiple use cases that benefit from container-based compute at the edge. Cisco’s container feature (IoX) directly addresses this trend today in energy and mining companies. Here are a few examples of edge software that address operating outcomes today. Each software solution has an instance running at the edge, in a container, on a Cisco router or switch.

    Cisco Cyber Vision

    What if your network’s routers and switches could give you visibility to the OT inventory on your network and identify any security anomalies that occur?  Cisco’s Cyber Vision can provide this visibility from your Cisco infrastructure. The Cyber Vision agents that monitor OT traffic and describe it in meta data for central analysis, live in containers on Cisco routers and switches. There is no need to invest in separate monitoring devices and an expensive backhaul network to reroute that traffic for analysis. It’s built in.

    Integrated Industrial Edge Compute
    Cyber Vision Architecture

    Industrial Network Solutions

    What if you could implement a small SCADA function in a router or switch that lives in a small cabinet or pumphouse? Industrial Network Solutions has integrated multiple container based agents that can perform all needed functions from a container on a router or switch. This avoids the old model of putting expensive purpose built boxes at every little site. It puts SCADA into locations with Ignition Edge, Node-RED and others where dedicated SCADA devices were not feasible before.

    Cheetah Networks

    What if you could objectively measure the communication experience that your remote site is experiencing? A small container app from Cheetah Networks gives you visibility to modem metrics and other local data points that were very difficult and cumbersome to aquire and manage with other solutions. As you guessed this container app can live in Cisco’s routers and switches without additional compute hardware.

    Cisco Edge Intelligence

    What if you need customized data management? Sometimes data acquisition requires a more flexible tool that can read data locally, normalize it and then send it to a central server as required. Edge Intelligence from Cisco is one such tool that’s highly programmable and comes with a wide variety of connectors and normalization capabilities. As with previous examples, it lives in a container app on Cisco’s routers and switches without additional compute hardware.

    And More


    These are just a few of the apps that have found a home in the small container space on Cisco routers and switches. The sweet spot for this approach is a small site that can’t justify a dedicated compute platform or an app that is tightly associated with network traffic on the router or switch.

    The edge compute trend is coming like a freight train and needs to be assessed across every enterprise. Before investing in a dedicated edge compute platform for every possible location, take a look at the capabilities already built into your network infrastructure. You may be surprised by the capability that’s already there.

    Making Your First Terraform File Doesn’t Have to Be Scary

    Making Your First Terraform File Doesn’t Have to Be Scary

    For the past several years, I’ve tried to give at least one Terraform-centric session at Cisco Live. That’s because they’re fun and make for awesome demos. What’s a technical talk without a demo? But I also see huge crowds every time I talk about Terraform. While I wasn’t an economics major, I do know if demand is this large, we need a larger supply!

    That’s why I decided to step back and focus to the basics of Terraform and its operation. The configuration applied won’t be anything complex, but it should explain some basic structures and requirements for Terraform to do its thing against a single piece of infrastructure, Cisco ACI. Don’t worry if you’re not an ACI expert; deep ACI knowledge isn’t required for what we’ll be configuring.

    The HCL File: What Terraform will configure


    A basic Terraform configuration file is written in Hashicorp Configuration Language (HCL). This domain-specific language (DSL) is similar in structure to JSON, but it adds components for things like control structures, large configuration blocks, and intuitive variable assignments (rather than simple key-value pairs).

    At the top of every Terraform HCL file, we must declare the providers we’ll need to gather from the Terraform registry. A provider supplies the linkage between the Terraform binary and the endpoint to be configured by defining what can be configured and what the API endpoints and the data payloads should look like. In our example, we’ll only need to gather the ACI provider, which is defined like this:

    terraform {

      required_providers {

        aci = {

          source = “CiscoDevNet/aci”

        }

      }

    }

    Once you declare the required providers, you have to tell Terraform how to connect to the ACI fabric, which we do through the provider-specific configuration block:

    provider "aci" {

    username = "admin"

    password = "C1sco12345"

    url      = "https://10.10.20.14"

    insecure = true

    }

    Notice the name we gave the ACI provider (aci) in the terraform configuration block matches the declaration for the provider configuration. We’re telling Terraform the provider we named aci should use the following configuration to connect to the controller. Also, note the username, password, url, and insecure configuration options are nested within curly braces { }. This indicates to Terraform that all this configuration should all be grouped together, regardless of whitespaces, indentation, or the use of tabs vs. spaces.

    Now that we have a connection method to the ACI controller, we can define the configuration we want to apply to our datacenter fabric. We do this using a resource configuration block. Within Terraform, we call something a resource when we want to change its configuration; it’s a data source when we only want to read in the configuration that already exists. The configuration block contains two arguments, the name of the tenant we’ll be creating and a description for that tenant.

    resource "aci_tenant" "demo_tenant" {

    name        = "TheU_Tenant"

    description = "Demo tenant for the U"

    }

    Once we write that configuration to a file, we can save it and begin the process to apply this configuration to our fabric using Terraform.

    The Terraform workflow: How Terraform applies configuration


    Terraform’s workflow to apply configuration is straightforward and stepwise. Once we’ve written the configuration, we can perform a terraform init, which will gather the providers from the Terraform registry who have been declared in the HCL file, install them into the project folder, and ensure they are signed with the same PGP key that HashiCorp has on file (to ensure end-to-end security). The output of this will look similar to this:

    [I] theu-terraform » terraform init


    Initializing the backend...


    Initializing provider plugins...

    - Finding latest version of ciscodevnet/aci...

    - Installing ciscodevnet/aci v2.9.0...

    - Installed ciscodevnet/aci v2.9.0 (signed by a HashiCorp partner, key ID 433649E2C56309DE)


    Partner and community providers are signed by their developers.

    If you'd like to know more about provider signing, you can read about it here:

    https://www.terraform.io/docs/cli/plugins/signing.html

    Terraform has created a lock file .terraform.lock.hcl to record the provider

    selections it made above. Include this file in your version control repository

    so that Terraform can guarantee to make the same selections by default when

    you run "terraform init" in the future.

    Terraform has been successfully initialized!

    You may now begin working with Terraform. Try running “terraform plan” to see any changes required for your infrastructure. All Terraform commands should now work.

    If you ever set or change modules or backend configuration for Terraform, rerun this command to reinitialize your working directory. If you forget, other commands will detect it and remind you to do so if necessary.

    Once the provider has been gathered, we can invoke terraform plan to see what changes will occur in the infrastructure prior to applying the config. I’m using the reservable ACI sandbox from Cisco DevNet  for the backend infrastructure but you can use the Always-On sandbox or any other ACI simulator or hardware instance. Just be sure to change the target username, password, and url in the HCL configuration file.

    Performing the plan action will output the changes that need to be made to the infrastructure, based on what Terraform currently knows about the infrastructure (which in this case is nothing, as Terraform has not applied any configuration yet). For our configuration, the following output will appear:

    [I] theu-terraform » terraform plan

    Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:

     + create

    Terraform will perform the following actions:


    # aci_tenant.demo_tenant will be created

    + resource "aci_tenant" "demo_tenant" {

    + annotation                    = "orchestrator:terraform"

    + description                   = "Demo tenant for the U"

    + id                            = (known after apply)

    + name                          = "TheU_Tenant"

    + name_alias                    = (known after apply)

    + relation_fv_rs_tenant_mon_pol = (known after apply)

    }


    Plan: 1 to add, 0 to change, 0 to destroy.

    ───────────────────────────────────────────────────────────────────────────────────────────────────────────────────────

    Note: You didn't use the -out option to save this plan, so Terraform can't guarantee to take exactly these actions if

    you run "terraform apply" now.

    We can see that the items with a plus symbol (+) next to them are to be created, and they align with what we had in the configuration originally. Great!  Now we can apply this configuration. We perform this by using the terraform apply command. After invoking the command, we’ll be prompted if we want to create this change, and we’ll respond with “yes.”

    [I] theu-terraform » terraform apply                                                      

    Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the

    following symbols:

      + create


    Terraform will perform the following actions:


      # aci_tenant.demo_tenant will be created

      + resource "aci_tenant" "demo_tenant" {

          + annotation                    = "orchestrator:terraform"

          + description                   = "Demo tenant for the U"

          + id                            = (known after apply)

          + name                          = "TheU_Tenant"

          + name_alias                    = (known after apply)

          + relation_fv_rs_tenant_mon_pol = (known after apply)

        }


    Plan: 1 to add, 0 to change, 0 to destroy.


    Do you want to perform these actions?

      Terraform will perform the actions described above.

      Only 'yes' will be accepted to approve.


      Enter a value: yes


    aci_tenant.demo_tenant: Creating...

    aci_tenant.demo_tenant: Creation complete after 3s [id=uni/tn-TheU_Tenant]


    Apply complete! Resources: 1 added, 0 changed, 0 destroyed.

    The configuration has now been applied to the fabric!  If you’d like to verify, log in to the fabric and click on the Tenants tab. You should see the newly created tenant.

    Finally – if you’d like to delete the tenant the same way you created it, you don’t have to create any complex rollback configuration. Simply invoke terraform destroy from the command line. Terraform will verify the state that exists locally within your project aligns with what exists on the fabric; then it will indicate what will be removed. After a quick confirmation, you’ll see that the tenant is removed, and you can verify in the Tenants tab of the fabric.

    [I] theu-terraform » terraform destroy                                                    

    aci_tenant.demo_tenant: Refreshing state... [id=uni/tn-TheU_Tenant]

    Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the

    following symbols:

      - destroy


    Terraform will perform the following actions:


      # aci_tenant.demo_tenant will be destroyed

      - resource "aci_tenant" "demo_tenant" {

          - annotation  = "orchestrator:terraform" -> null

          - description = "Demo tenant for the U" -> null

          - id          = "uni/tn-TheU_Tenant" -> null

          - name        = "TheU_Tenant" -> null

        }



    Plan: 0 to add, 0 to change, 1 to destroy.


    Do you really want to destroy all resources?

      Terraform will destroy all your managed infrastructure, as shown above.

      There is no undo. Only 'yes' will be accepted to confirm.


      Enter a value: yes


    aci_tenant.demo_tenant: Destroying... [id=uni/tn-TheU_Tenant]

    aci_tenant.demo_tenant: Destruction complete after 1s


    Destroy complete! Resources: 1 destroyed.

    Complete Infrastructure as Code lifecycle management with a single tool is pretty amazing, huh?

    A bonus tip


    Another tip regarding Terraform and HCL relates to the workflow section above. I described the use of curly braces to avoid the need to ensure whitespace is correct or tab width is uniform within the configuration file. This is generally a good thing, as we can focus on what we want to deploy rather than minutiae of the config. However, sometimes it helps when you format the configuration in a way that’s aligned and easier to read, even if it doesn’t affect the outcome of what is deployed.

    In these instances, you can invoke terraform fmt within your project folder, and it will automatically format all Terraform HCL files into aligned and readable text. You can try this yourself by adding a tab or multiple spaces before an argument or maybe between the = sign within some of the HCL. Save the file, run the formatter, and then reopen the file to see the changes. Pretty neat, huh?

    Secure Multicloud Infrastructure with Cisco Multicloud Defense

    It’s a multicloud world!


    Today applications are no longer restricted to the boundaries of a data center; applications are deployed everywhere – this change brings a need for a solution that can provide end-to-end visibility, control, policy management, and ease of management.

    Market Trend


    Organizations are embracing the power of the public cloud because it provides agile, resilient, and scalable infrastructure, enabling them to maximize business velocity. A recent study shows that 82% of IT leaders have adopted hybrid cloud solutions, combining private and public clouds. Additionally, 58% of these organizations are using between two and three public clouds1, indicating a growing trend towards multicloud environments. As organizations lean further into multicloud deployments, security teams find they are playing catch up, tirelessly attempting to build a security stack that can keep up with the agility and scale of their cloud infrastructure. Teams also face a lack of unified security controls across their environments. By definition, cloud service provider security solutions are not designed to achieve end-to-end visibility and control in the multicloud world, hardening silos and creating greater security gaps. Organizations need a cloud-agnostic solution that unifies security controls across all environments while securing workloads at cloud speed and scale.

    Cisco Multicloud Defense is a highly scalable, on-demand “as-a-Service” solution that provides agile, scalable, and flexible security to your multicloud infrastructure. It unifies security controls across cloud environments, protects workloads from every direction, and drives operational efficiency by leveraging secure cloud networking.

    Secure cloud networking can be broken down into three pillars:

    • Security: Provides a full suite of security capabilities for workload protection
    • Cloud: Integrates with cloud constructs, enabling auto-scale and agility
    • Networking: Seamlessly and accurately inserts scalable security across clouds without manual intervention

    One of the key benefits of Cisco Multicloud Defense is not only its ability to unify security controls across environments but enforce those policies dynamically. With dynamic multicloud policy management, you can:

    • Keep policies up to date in near-real time as your environment changes.
    • Connect continuous visibility and control to discover new cloud assets and changes, associate tag-based business context, and automatically apply the appropriate policy to ensure security compliance.
    • Power and protect your cloud infrastructure with security that runs in the background via automation, getting out of the way of your cloud teams.
    • Mitigate security gaps and ensure your organization stays secure and resilient.

    Another key benefit of Multicloud Defense is how it adds enforcement points (PaaS) in both distributed and centralized architectures.

    Cisco Multicloud Defense Overview


    Cisco Multicloud Defense uses a common principle in public clouds and software-defined networking (SDN) which decouples the control and data plane, translating to the Multicloud Defense Controller and the Multicloud Defense Gateways.

    The Multicloud Defense Gateway(s) are delivered as Platform-as-a-Service (PaaS) in AWS, Azure, Google Cloud Platform (GCP), and Oracle Cloud Infrastructure (OCI). These gateways are delivered, managed, and orchestrated by a SaaS-based Multicloud Defense Controller.

    Secure Multicloud Infrastructure with Cisco Multicloud Defense
    Figure 1: Cisco Multicloud Defense Overview

    • Multicloud Defense Controller (Software-as-a-Service): The Multicloud Defense Controller is a highly reliable and scalable centralized controller (control plane) that automates, orchestrates, and secures multicloud infrastructure. It runs as a Software-as-a-Service (SaaS) and is fully managed by Cisco. Customers can access a web portal to utilize the Multicloud Defense Controller, or they may choose to use Terraform to instantiate security into the DevOps/DevSecOps processes.
    • Multicloud Defense Gateway (Platform-as-a-Service): The Multicloud Defense Gateway is an auto-scaling fleet of security software with a patented flexible, single-pass pipelined architecture. These gateways are deployed as Platform-as-a-Service (PaaS) into the customer’s public cloud account(s) by the Multicloud Defense Controller, providing advanced, inline security protections to defend against external attacks, block egress data exfiltration, and prevent the lateral movement of attacks.

    Multicloud Defense Gateways


    In the Cisco Multicloud Defense solution, organizations can use the controller to deploy highly scalable and resilient Egress Gateways or Ingress Gateways into their public cloud account(s).

    Egress Gateway: Protect outbound and east-west traffic. The egress gateway provides security capabilities like FQDN filtering, URL filtering, data loss prevention (DLP), IPS/IDS, antivirus, forward proxy, and TLS decryption.

    Ingress Gateway: Protects inbound traffic and provides security capabilities like web application firewall (WAF), IDS/IPS, Layer-7 protection, DoS protection, antivirus, reverse proxy, and TLS decryption.

    Note: Multicloud Defense Gateways are an auto-scaling fleet of instances across two or more availability zones, providing agility, scalability, and resiliency.

    Figure 2 shows security capabilities of the ingress and egress Multicloud Defense Gateway.

    Secure Multicloud Infrastructure with Cisco Multicloud Defense
    Figure 2: Cisco Multicloud Defense Gateway

    The gateway uses a single pass architecture to provide:

    • High throughput and low latency
    • Reverse proxy, forward proxy, and forwarding mode
    • Flexibility in selecting relevant advanced network security inspection engines, including TLS decryption and re-encryption, WAF (HTTPS and web sockets), IDS/IPS, antivirus/anti-malware, FQDN and URL filtering, DLP

    Security Models


    This solution provides a flexible way for security insertion in the customer’s infrastructure using three highly scalable and automated deployment models (centralized, distributed, and combined).

    Centralized security model

    In the centralized security model, the Multicloud Defense Controller seamlessly adds gateways in the centralized security VPC/VNet/VCN. In this architecture, ingress and egress traffic is sent to a centralized security VPC/VNet/VCN for inspection before it is sent to the destination. This architecture ensures scalability, resiliency, and agility using cloud deployment best practices.

    Figure 3 shows egress and ingress gateways in a security VPC/VNet/VCN.

    • For scalability, autoscaling is supported.
    • For resiliency, auto-scaled instances are deployed in multi-availability zones.

    Secure Multicloud Infrastructure with Cisco Multicloud Defense
    Figure 3: Centralized Security Model

    In a centralized security model, gateways are deployed in a hub inside the customer’s cloud account. However, customers can choose to have multiple hubs across accounts/subscriptions.

    Distributed security model

    In the distributed security model, the Multicloud Defense Controller seamlessly adds gateways in each VPC/VNet/VCN. In this architecture, ingress, and egress traffic stays local in the VPC/VNet/VCN.

    Based on direction, traffic flow is inspected by egress or ingress gateways. This deployment ensures scalability, resiliency, and agility using cloud deployment best practices.

    Figure 4 shows egress and ingress gateways in each VPC/VNet/VCN.

    • For scalability, autoscaling is supported.
    • For resiliency, auto-scaled instances are deployed in multi-availability zones.

    Secure Multicloud Infrastructure with Cisco Multicloud Defense
    Figure 4: Distributed Security Model

    Combined security model (Centralized + Distributed)

    This security model uses centralized and distributed models. In this case, some flows are protected by gateways deployed in the security VPC/VNet/VCN, and some flows are protected by gateways in the VPC/VNet/VCN.

    Based on the traffic flow, traffic is inspected by egress or ingress gateways. This deployment ensures scalability, resiliency, and agility using cloud deployment best practices.

    Figure 5 shows egress and ingress gateways in a centralized security VPC/VNet/VCN in addition to gateways deployed in the application VCPs/VNets/VCNs.

    • For scalability, autoscaling is supported.
    • For resiliency, auto-scaled instances are deployed in multi-availability zones.

    Segmentation (east-west)

    Figure 8 shows intra and inter-VPC/VNet/VCN traffic protection in a centralized and distributed security model.

    • In the centralized security model, intra and inter-VPC/VNet/VCN traffic is inspected by gateways deployed in the security VPC/VNet/VCN.
    • In the distributed security model, intra-VPC/VNet/VCN traffic is inspected by gateways deployed in the application VPC/VNet/VCN.
    • Gateways are auto-scale and multi-AZ aware.

    Secure Multicloud Infrastructure with Cisco Multicloud Defense
    Figure 8: Segmentation (East-West) traffic flow

    URL & FQDN filtering for egress traffic

    URL & FQDN filtering prevents exfiltration and attacks that use command-and-control. The Multicloud Defense Gateway enforces URL & FQDN-based filtering in a centralized or distributed deployment model.

    • URL filtering requires TLS decryption on the gateway.
    • FQDN-based filtering can be enforced on encrypted traffic flows.

    Secure Multicloud Infrastructure with Cisco Multicloud Defense
    Figure 8: URL & FQDN filtering for cloud egress

    Coming soon: Multicloud Networking use cases

    In our upcoming release (2HCY23), we are adding a set of Multicloud Cloud Networking use cases that enable secure connectivity — bringing all cloud networks together.

    Multicloud Networking: Cloud-to-Cloud Networking

    An egress gateway with VPN capability provides a secure connection to other cloud infrastructures. The egress gateway is delivered as-a-Service and provides resiliency and autoscaling. This architecture requires deploying the egress gateways with VPN capability “ON.” These gateways use IPsec connectivity for a secure interconnection.

    Secure Multicloud Infrastructure with Cisco Multicloud Defense
    Figure 9: Cloud-to-Cloud Networking (IPsec)

    Multicloud Networking: Site-to-Cloud Networking

    An egress gateway with VPN capability provides a secure connection to on-premises infrastructure. This architecture requires deploying the egress gateways with VPN capability “ON” in security VPC/VNet/VCN and a device at the data center edge for IPsec termination.

    Secure Multicloud Infrastructure with Cisco Multicloud Defense
    Figure 10: Site-to-Cloud Networking (IPsec)
