Implement Zero Trust Network for Microservices using TSB

Today, every major organization is going through a massive digital transformation, adopting cloud, mobile, microservices, and container technologies to deliver services efficiently, meet critical business demands, and catch up with market expectations. Organizations’ Platform and DevOps teams have to model distributed and multi-cloud applications and services accessible from anywhere and anytime to be agile. This has given rise to two significant trends within the organizations:

  1. As a growing number of organizations adopt multi-cloud, they deploy their applications into the public cloud (Google, Amazon, Azure, etc.), which means that the data is out of their perceived safety of on-prem data centers.
  2. Organizations use microservices and distributed architecture to achieve agility and scale.

Tetrate’s Year in Review: 2021

As we shift into 2022, we’d like to share some of the highlights and milestones Tetrate has reached in 2021 with your support. Since its founding in March 2018, Tetrate has been growing its capacity to fulfill what it set out to do– to reimagine application networking. This, our fourth year, was bookended by our Series B fundraising round led by Sapphire Ventures and our recent designation as a Gartner Cool Vendor for Cloud Computing. Here’s a snapshot of top company milestones we accomplished together in 2021:

The debate in the community about Istio and service mesh

You can use Istio to do multi-cluster management, API Gateway, and manage applications on Kubernetes or virtual machines. In my last blog, I talked about how service mesh is an integral part of cloud native applications. However, building infrastructure can be a big deal. There is no shortage of debate in the community about the practicability of service mesh and Istio– here’s a list of common questions and concerns, and how to address them.

  • Is anyone using Istio in production?
  • What is the impact on application performance due to the many resources consumed by injecting sidecar into the pod?
  • Istio supports a limited number of protocols; is it scalable?
  • Will Istio be manageable? – Or is it too complex, old services too costly to migrate, and the learning curve too steep?

I will answer each of these questions below.

New in Istio 1.12: Wasm-based extensions and ecosystem

New WebAssembly infrastructure in Istio makes it easy to inject additional functionality into mesh deployments

Three years in the making, Istio now has a powerful extension mechanism for adding custom and third-party Wasm modules to sidecars in the mesh. Tetrate engineers Takeshi Yoneda and Lizan Zhou have been instrumental in making this happen. This post will cover the basics of Wasm in Istio and why it matters followed by a short tutorial on building your own Wasm plugin and deploying it to the mesh.

Tetrate now available in AWS Marketplace

For most organizations, modernizing enterprise applications is a journey. During this journey, it’s not uncommon for applications to migrate from datacenters to clouds, VMs to containers, with concerns and requirements spanning from edge to workload and everywhere in between––often all at the same time. Istio, the most widely deployed and de facto standard service mesh, helps enterprises manage application modernization along every step of that journey. And now, Tetrate Istio Subscription (TIS) is available for Amazon customers on the AWS Marketplace, making it the first hardened Istio subscription with enterprise support available there.

Multi-site failover with Tetrate Service Bridge

Microservices bring many benefits to any organization’s software practice. It can be efficiency, speed of changes and improvements, granularity of control over application behavior, solid and stable end-user experience with multiple instances of the service running in parallel, and also global reach with ability to get services closer to the user geographical location and more.

EKS is Anywhere and so is Tetrate

Tetrate works with Amazon EKS and EKS Anywhere to bring seamless connectivity and management to Kubernetes applications both on-premises and in the cloud. One of Tetrate’s founding goals is to enable our customers to manage their applications everywhere––from edge to workload, between services and VMs, in datacenters and the cloud––and to do it securely, reliably, and scalably while providing a consistent experience to IT ops and developers across these environments.

That goal aligns perfectly with EKS Anywhere, Amazon’s new Kubernetes offering that reaches beyond AWS. Amazon Elastic Kubernetes Service (EKS) is a managed compute platform for containers that allows customers to avoid the undifferentiated heavy lifting involved in using roll-your-own Kubernetes to run modern applications on AWS. EKS Anywhere is a new deployment option for Amazon EKS that enables customers to easily create and operate Kubernetes clusters on-premises, including virtual machines (VMs) and bare metal servers. With EKS Anywhere, Amazon offers its customers a consistent Kubernetes experience both on-premises and in the cloud.
