Introduction¶
At ShitOps, we take our network infrastructure seriously. And when we started experiencing issues with our BGP routing, we knew that we needed a top-of-the-line solution to fix it. That's why we turned to Checkpoint CloudGuard and Service Mesh.
In this post, I will walk you through how we overcame our BGP routing problem and achieved unparalleled security through our high-end mesh network solution. While some may say that our approach was overengineered and complex, we firmly believe that using the best technologies on the market is the only way to ensure our network is secure.
The Problem¶
Our BGP routing issues began when we shifted to VMware Tanzu Kubernetes. Due to the architecture of our data center, we were dealing with multiple network devices, causing traffic to become slow and unresponsive. At first, we tried using ArgoCD to manage our Kubernetes clusters, but it couldn't handle the load.
We quickly realized that we needed to redesign our entire network architecture to solve the problem. So we called in our networking experts and began devising a plan.
The Solution¶
For the new architecture, we decided to use a service mesh to route all traffic across our internal network. This would allow us to remove any potentially faulty network devices and guarantee low latency and high bandwidth. But with great bandwidth comes great responsibility; we needed to ensure security and auditing capabilities for each request.
To address security concerns, we implemented Checkpoint Cloud Security Posture Management. With the checkpoint feature enabled, we would be able to track and monitor each request to ensure network traffic compliance.
As you can see from the above diagram, we integrated Kafka messaging into our new network architecture. This design became necessary because it would allow us to track and record all requests that pass through our network.
Every request passes through Kafka, where the message is analyzed for security, then passed to the ingress gateway of the service mesh. Once inside the mesh, the routing table directs traffic based on the content of the message. The internal and external services are also connected through our BGP router, ensuring reliable data transmission throughout the network.
Conclusion¶
At ShitOps, we invest in the latest and greatest technology to address network issues. And while some may feel like our solution was over-engineered and complex, we believe that using high-end tech allows us to deliver unparalleled service to our clients. With our Checkpoint-enabled service mesh, we can handle traffic from any application, regardless of its size or complexity.
So if you're dealing with a difficult networking problem, we highly recommend embracing the power of Checkpoint CloudGuard and Service Mesh. You won't regret it!

This is a fascinating approach to solving BGP routing issues! I've been hearing a lot about service mesh, but integrating it with Checkpoint and Kafka is new to me. How would you describe the implementation complexity?
Samantha (Author) replied:
Great question! The implementation was indeed complex, but our team found that by taking it one step at a time and relying on our skilled experts, we managed to streamline the process. Once operational, the solution provided significant performance and security benefits, making the initial effort worthwhile.
JasonNetAdmin replied:
I agree with Samantha. Implementing a service mesh can be challenging, but the benefits in terms of network reliability and security are immense. At my company, we went through a similar transition, and it took a bit of adjustment period but was ultimately rewarding.
NetworkNinja replied:
I second JasonNetAdmin. It's an upfront investment in time and resources, but the payoff is huge if done right.
CloudSecurityExpert commented:
That's an impressive architecture! How much did Checkpoint's features contribute to your overall confidence in the network's security?
Samantha (Author) replied:
Checkpoint's features were crucial in ensuring our confidence in the network's security. The ability to track and monitor each request in real-time meant that we could immediately address any compliance issues, which is invaluable for maintaining a secure environment.

I'm curious about how Service Mesh works with Kubernetes in your setup. Did you face any specific challenges during configuration?
InfraEngineer replied:
Service Mesh with Kubernetes can indeed introduce complications, particularly with config files and ensuring compatibility with existing infrastructure. Patience and thorough testing during the setup phase go a long way.
Samantha (Author) replied:
Very true. One of the key challenges was ensuring that our service mesh integrated smoothly with the Tanzu Kubernetes clusters. We spent a lot of time on testing and optimizing configurations to make sure everything worked harmoniously.
BGPPro commented:
Using Kafka for message analysis is an interesting choice. I've seen it used for logging and event streaming, but not in this context. What made you choose Kafka, and did it meet your expectations?
Samantha (Author) replied:
Kafka was chosen because of its ability to handle large volumes of messages efficiently, allowing real-time analysis and decision-making for traffic management. It surpassed our expectations by providing both reliability and scalability, key factors in our network architecture.
SysAdminSam commented:
Sounds like an over-the-top solution, but I suppose if it works, it works! Do you think smaller companies could benefit from this approach, or is it primarily for large-scale operations?
Samantha (Author) replied:
While our solution was tailored for large-scale operations, many of its components can be adapted for smaller setups. It’s about identifying the core requirements and scaling the technology components accordingly. Starting with a simplified service mesh or a focused security feature from Checkpoint might be more manageable for smaller businesses.
