How to avoid common mistakes when adopting AI

How to avoid common mistakes when adopting AI

I’ll never cease to be amazed by the Olympic runners. As someone who has logged my fair share of runs, I’m totally mesmerized by these runners’ paces. I get short of breath just watching them on my TV.

Olympic runners are worthy of our admiration. But these athletes didn’t wake up the day before the Olympics and decide to hop a flight to Paris. Their freedom to run at break-neck speed required years of discipline and training.

They had a method. They trained. Step-by-step. Day-by-day. Until, one day in Paris, they were finally able to harness this power.

This is how we should view AI.

Just like training to be expert runner, a recent Gartner® report (which you can access here complimentarily) emphasizes the importance of a measured approach. According to Gartner, “The building blocks of AI adoption are various and diverse in real life. Nevertheless, when assembled, they follow general principles that support AI progress.” Gartner mentions that “applying these principles is necessary to set realistic expectations, avoid common pitfalls, and keep AI initiatives on track.”

You can’t be in the Olympics on day one — nor do you want to be in the Olympics on day one. Growing into an AI-mature organization is about following a roadmap — a proven method — and not biting off more than you can chew.

By defining a clear strategy, communicating frequently, and setting measurable outcomes, organizations can optimize their results and avoid common pitfalls.

The Gartner phased approach to AI adoption


AI can help you classify and understand complex sets of data, automate decisions without human intervention, and generate anything from content to code by utilizing large repositories of data. However, if you underestimate the importance of getting your priorities in order first, you may be forced to learn the hard way and suffer delays and frustration.

In the report, Gartner offers an AI adoption framework where “organizations will avoid major pitfalls and maximize the chances of successful AI implementation.” Gartner tells organizations to “use the AI adoption curve to identify and achieve your goals for activities that increase AI value creation by solving business problems better, faster, at a lower cost and with greater convenience.”

Let’s look at our takeaways from these key phases.

Phase 1. Planning

Start small. Getting into peak running condition starts with short runs. Identify and recruit an internal champion to help socialize efforts and secure support from key stakeholders. Establish three to six use cases with measurable outcomes that benefit your line of business.

Phase 2. Experimentation

Practice makes perfect. Invest in the humans, processes, and technology that ease the transition between phases, such as funding a Center of Excellence (COE) and teaching practical knowledge of cloud AI APIs. Build executive awareness with realistic goals. Experiment. Break things. And don’t be afraid to change course on your strategy. Be flexible and know when to pivot!

Phase 3. Stabilization

At this point in the process, you have a basic AI governance model in place. The first AI use cases are in production, and your initial AI implementation team has working policies to mitigate risks and assure compliance. This stage is referred to as the “pivotal point” — it is all about stabilizing your plans, so you are ready to expand with additional, more complex use cases.

With strategic objectives defined, budgets in place, AI experts on hand, and technology at the ready, you can finalize an organizational structure and complete the processes for the development and deployment of AI.

Phase 4. Expansion

High costs are common at this stage of AI adoption as initial use cases prove their value and momentum builds. It’s natural to hire more staff, upskill employees, and incur infrastructure costs as the wider organization takes advantage of AI in daily operations.

Track spending and be sure to demonstrate progress against goals to learn from your efforts. Socialize outcomes with stakeholders for transparency. Remember, just like run training, it’s a process of steady improvement. Track your results, show progress, and build on your momentum. As you grow more experienced, you should expand, evolve, and optimize. Providing your organization sees measurable results, consider advancing efforts to support more high risk/high reward use cases.

Phase 5. Leadership

AI will succeed in an organization that fosters transparency, training, and shared usage of across business units, not limited to exclusive access. Build an “AI first” culture from the top down, where all workers understand the strengths and weaknesses of AI to be productive and innovate security.

Lessons from the AI graveyard


AI adoption will vary and that’s okay! Follow these steps to ensure you stay on the path most appropriate for your business. Avoid common mistakes of caving to peer pressure and focus on creating a responsible use of AI that enables you to reduce technology risks and work within the resources currently available. Here’s some advice from those that hit a speedbump or two.

  1. Choose your first project carefully; most AI projects fail to deploy as projected.
  2. Don’t underestimate the time it takes to deploy.
  3. Ensure your team has the right skills, capacity, and experience to take advantage of AI trends.

No two AI journeys are the same


According to Gartner, “By 2025, 70% of enterprises will have operationalized AI architectures due to the rapid maturity of AI orchestration platforms.” Don’t get discouraged if you are in the 30% that may not be on that path.

Every organization will choose to adopt AI at the rate that is right for them. Some organizations consider themselves laggards, but they are learning from their peers and are taking the necessary steps to create a successful AI implementation. “By 2028, 50% of organizations will have replaced time-consuming bottom-up forecasting approaches with AI, resulting in autonomous operational, demand, and other types of planning.”

Read the complementary report to learn more about key adoption indicators and recommendations to ensure data is central to your strategy—from determining availability, to integration, access and more. This Gartner report provides hands-on, practical tips to help build confidence with tips and recommendations to help embrace the AI journey from planning to expansion.

Optimizing AI Workloads with NVIDIA GPUs, Time Slicing, and Karpenter

Maximizing GPU efficiency in your Kubernetes environment


In this article, we will explore how to deploy GPU-based workloads in an EKS cluster using the Nvidia Device Plugin, and ensuring efficient GPU utilization through features like Time Slicing. We will also discuss setting up node-level autoscaling to optimize GPU resources with solutions like Karpenter. By implementing these strategies, you can maximize GPU efficiency and scalability in your Kubernetes environment.

Additionally, we will delve into practical configurations for integrating Karpenter with an EKS cluster, and discuss best practices for balancing GPU workloads. This approach will help in dynamically adjusting resources based on demand, leading to cost-effective and high-performance GPU management. The diagram below illustrates an EKS cluster with CPU and GPU-based node groups, along with the implementation of Time Slicing and Karpenter functionalities. Let’s discuss each item in detail.

Optimizing AI Workloads with NVIDIA GPUs, Time Slicing, and Karpenter

Basics of GPU and LLM


A Graphics Processing Unit (GPU) was originally designed to accelerate image processing tasks. However, due to its parallel processing capabilities, it can handle numerous tasks concurrently. This versatility has expanded its use beyond graphics, making it highly effective for applications in Machine Learning and Artificial Intelligence.

Optimizing AI Workloads with NVIDIA GPUs, Time Slicing, and Karpenter

When a process is launched on GPU-based instances these are the steps involved at the OS and hardware level:

  • Shell interprets the command and creates a new process using fork (create new process) and exec (Replace the process’s memory space with a new program) system calls.
  • Allocate memory for the input data and the results using cudaMalloc(memory is allocated in the GPU’s VRAM)
  • Process interacts with GPU Driver to initialize the GPU context here GPU driver manages resources including memory, compute units and scheduling
  • Data is transferred from CPU memory to GPU memory
  • Then the process instructs GPU to start computations using CUDA kernels and the GPU schedular manages the execution of the tasks
  • CPU waits for the GPU to finish its task, and the results are transferred back to the CPU for further processing or output.
  • GPU memory is freed, and GPU context gets destroyed and all resources are released. The process exits as well, and the OS reclaims the resource

Compared to a CPU which executes instructions in sequence, GPUs process the instructions simultaneously. GPUs are also more optimized for high performance computing because they don’t have the overhead a CPU has, like handling interrupts and virtual memory that is necessary to run an operating system. GPUs were never designed to run an OS, and thus their processing is more specialized and faster.

Large Language Models


A Large Language Model refers to:

  • “Large”: Large Refers to the model’s extensive parameters and data volume with which it is trained on
  • “Language”: Model can understand and generate human language
  • “Model”: Model refers to neural networks

>>> print all primes between 1 and n
Here is a Python solution that prints all prime numbers between 1 and `n`:
```Python
def print_primes(n):
    for possiblePrime in range(2, n + 1):
        # Assume number is prime until shown it is not. 
        isPrime = True
        for num in range(2, int(possiblePrime ** 0.5) + 1):
            if possiblePrime % num == 0:
                isPrime = False
                break
        if isPrime:
            print(possiblePrime)
n = int(input("Enter the number: "))
print_primes(n)
```
In this code, we loop through all numbers from `2` to `n`. For each number, we assume it's prime and then check if it has any 
divisors other than `1` and itself. If it does, then it's not a prime number. If it doesn't have any divisors, then it is a 
prime number.
The reason why we only need to check up to the square root of the number is because a larger factor of the number would be a 
multiple of smaller factor that has already been checked.
Please note that this code might take some time for large values of `n` because it's not very efficient. There are more 
efficient algorithms to find prime numbers, but they are also more complex.

Communications Compliance is Taking Center Stage in the Boardroom

Communications Compliance is Taking Center Stage in the Boardroom

Within the modern governance landscape in financial services, communications compliance has emerged as a critical issue, spurred by the staggering fines for unmonitored communications that have surpassed $2 billion USD in the United States alone. In February 2024, an additional 16 firms faced SEC fines totaling $81 million, signaling a zero-tolerance stance by regulators against compliance violations.

The Cisco and Theta Lake partnership, established in 2018, reflects a strategic response to these challenges. Theta Lake enhances the security and compliance features of Cisco’s Webex collaboration suite. This joint solution ensures institutions can safely harness the power of Webex’s functionalities, while significantly reducing the risk of penalties, increasing user satisfaction, and enhancing ROI (return on investment).

Theta Lake’s “Digital Communications Governance, Compliance, and Security Survey” for 2023/24, sheds light on the evolving landscape. With independent responses from over 600 IT and compliance professionals, the Theta Lake report reveals that 40% of firms have now elevated communications compliance to a board-level concern, underscoring the pressing demand for a revamped compliance and security framework for Unified Communications and Collaboration (UCC) tools that are integral to the modern workplace.

Why Are Firms Reevaluating Their Communications Compliance Strategies?


The survey indicates a widespread reassessment of communications compliance strategies in financial services, with 77% of respondents revising their approaches, 17% planning to do so, and 45% considering a complete overhaul. Traditional methods often fail to seamlessly capture, retain, and supervise across diverse communication platforms, leading to inefficiencies and compliance lapses. To counter these challenges, organizations are restricting key features that users want and need, inadvertently pushing employees towards unmonitored channels.

Theta Lake, in partnership with Cisco Webex, offers a purpose-built compliance, supervision, and security solution that integrates seamlessly across the Webex Suite, whether content is displayed, shared, spoken, or written. This solution brings significant value to leading organizations, including some of Webex’s largest customers—six of the top ten North American banks.

Where Should Organizations Begin When Overhauling Their Digital Communications Strategy?


Addressing compliance complexities requires a structured, proactive approach. In a rapidly evolving digital landscape, organizations must anticipate regulatory expectations and strategically overhaul their digital communications governance.

Cisco and Theta Lake recommend a three-point strategy:

  • Effective Data Capture: Accurate and reliable record keeping starts by capturing the correct data at its source, along with its context and time of origin. This step is crucial for reconciliation and reporting.
  • Record Navigation: With comprehensive record keeping across various channels, searching and navigating records and their interwoven communications becomes both possible and efficient.
  • AI-Enhanced Compliance Scaling: AI (Artificial Intelligence) technology, specifically tailored for compliance, helps manage and oversee vast amounts of communication records, enabling institutions to identify and mitigate risks and maintain robust compliance standards.

Theta Lake: A Cisco SolutionsPlus Partner


The Cisco SolutionsPlus program features tested Cisco Compatible products. As a SolutionsPlus partner focused on collaboration and security, Theta Lake’s solution for the Webex Suite is available for purchase through the Cisco price list. This includes fully compliant capture, archiving (in existing systems or Theta Lake’s SEC-17a-4 compliant environment), and built-in policy-based AI-enabled risk detection/remediation/redaction capabilities for:

  • Webex Calling & Customer Experience Essentials (New!): Voice Recordings, Business Texts (SMS), and Call Detail Records.
  • Webex Meetings & Selective In-Meeting Communications: Video recordings, and selective archiving of any or all meeting components including audio or in-meeting eComms (such as chat, polling, Q&A, transcripts, and closed captioning).
  • Webex Messaging: All content, replies, and reactions—including files and rich media (like images and GIFs).
  • Polling/Slido: All content including polls, Q&A, surveys, and more.
  • Webex Connect: Archiving & supervision support of log exports via SMTP or Rest API for SMS and omnichannel content.

In an era of intense regulatory oversight, Cisco and Theta Lake’s joint solutions have transitioned from a strategic asset to an essential requirement for financial services organizations aiming to ensure robust communications compliance.

Protecting Against regreSSHion with Secure Workload

On July 1, 2024, the Qualys Threat Research Unit (TRU) disclosed an unauthenticated, remote code execution vulnerability that affects the OpenSSH server (sshd) in glibc-based Linux systems.

Now we have seen how CVE-2024-6387 has taken the internet by storm, making network security teams scramble to protect the networks while app owners patch their systems.

Secure Workload helps organizations get visibility of application workload traffic flows and implement microsegmentation to reduce the attack surface and contain lateral movement, mitigating the risk of ransomware.

Below are multiple ways in which Secure Workload can be leveraged to get visibility of affected application workloads and enforce segmentation policies to mitigate the risk of workloads being compromised.

1. Visibility of SSH Traffic Flows

According to the Qualys Threat Research Unit, the versions of OpenSSH affected are those below 4.4p1, as well as versions 8.5p1 through 9.8p1, due to a regression of CVE-2006-5051 introduced in version 8.5p1.

With Secure Workload, it is easy to search for traffic flows generated by any given OpenSSH version, allowing us to spot affected workloads right away and act. By using the following search attributes, we can easily spot such communications:

◉ Consumer SSH Version
◉ Provider SSH Version

2. Visibility of OpenSSH Package Version in Workloads

Navigate to Workloads > Agents > Agent List and click on the affected workloads. On the Packages tab, filter for the “openssh” name and it will search for the current OpenSSH package installed on the workload.

3. Visibility of CVE-ID Vulnerability in Workloads

Navigate to Vulnerabilities tab, and a quick search for the CVE ID 2024-6387 will search the current vulnerabilities on the workload:

4. Mitigating Risk of regreSSHion

Once the relevant workloads are spotted, there are three main avenues to mitigate the risk: either by microsegmenting the specific application workload, implementing organization-wide auto-quarantine policies to proactively reduce the attack surface, or performing a virtual patch with Secure Firewall.

◉ Microsegmentation: Microsegmentation policies allow you to create fine-grained allow-list policies for application workloads. This means that only the specified traffic flows will be permitted, denying any other traffic that might be generated from the workload.

◉ Forensic Rules: Secure Workload comes with 39 out-of-the-box MITRE ATT&CK rules to look for techniques, tactics, and procedures leveraged by adversaries. It is also possible to create custom forensic rules to track certain process activities, such as privilege escalation performed by processes. The system can also generate alerts and send them to the Secure Workload UI and SIEM systems.
