Shift-left is an approach to software development and operations that emphasizes testing, monitoring, and automation earlier in the software development lifecycle. The goal of the shift-left approach is to prevent problems before they arise by catching them early and addressing them quickly. When you identify a scalability issue or a bug early, it is quicker and more cost-effective to resolve it.

by David Vroom, James Mulcahy, Ling Yuan, Rob Gulewich In this post we discuss Netflix’s adoption of service mesh: some history, motivations, and how we worked with Kinvolk and the Envoy community on a feature that streamlines service mesh adoption in complex microservice environments: on-demand cluster discovery. A brief history of IPC at Netflix Netflix was early to the cloud, particularly for large-scale companies: we began the migration in 2008, and by 2010, Netflix streaming was fully run o

MySQL users can easily be confused by the seemingly infinite differences between MySQL and PostgreSQL. The good news is that for someone familiar with MySQL, they have the basics of databases covered and can explore some of the treasures to be discovered in the new PostgreSQL environment. One of the interesting facets that you need to explore that has no corresponding counterpart in the MySQLverse is table inheritance.

PostgreSQL allows its users to set parameters at different scopes, and the same parameter can be specified at different places and using different methods. And there could be conflicts. Someone might be wondering why certain changes are not coming into effect, so it is important to understand/recollect the scope and priority of settings. In this blog, I am trying to list the options available for users and list them in increasing order of priority.

Intro to Istio Observability Using Prometheus Istio service mesh abstracts the network from the application layers using sidecar proxies. You can implement security and advance networking policies to all the communication across your infrastructure using Istio. But another important feature of Istio is observability. You can use Istio to observe the performance and behavior of all your microservices in your infrastructure (see the image below).

One of my current talks focuses on Observability in general and Distributed Tracing in particular, with an OpenTelemetry implementation. In the demo, I show how you can see the traces of a simple distributed system consisting of the Apache APISIX API Gateway, a Kotlin app with Spring Boot, a Python app with Flask, and a Rust app with Axum. Earlier this year, I spoke and attended the Observability room at FOSDEM.

When deploying Kubernetes resources in a cluster, it is sometimes necessary to deploy them in a specific order. For example, a Custom Resource Definition (CRD) must exist before any custom resources of that type can be created. Sveltos can help you solve this problem by allowing you to specify the order in which Kubernetes resources are deployed.

If you are running a distributed system where each request talks to more than a couple of services, databases, and a queuing system, pinpointing the cause of an issue is not a trivial affair. The complexity increases as the number of services increases, as east-west traffic goes up, as teams get split up, and as data tends to eventual consistency. There are a plethora of tools aiming to solve this problem to various degrees.

Can zero trust and positive user experiences coexist within the government? On the one hand, the United States has mandates such as the White House Executive Order (EO) 14028 on “Improving the Nation’s Cybersecurity.” This mandate directs federal agencies to advance toward a zero-trust architecture that “eliminates implicit trust in any one element, node, or service.
