Twitter Google+ LinkedIn Github StackoverflowNo doubt, if you’ve been paying attention to technology trends, you’ve seen the rise in interest of “serverless”. In some accounts, “serverless” is billed as the “next application architecture” style. I’ve even h...
I’ve recently started giving a talk about the evolution of integration and the adoption of service mesh, specifically Istio. I’ve been excited about Istio ever since I first heard about it back in January 2017; i...
I’m fortunate to have a few sessions at Red Hat Summit next week (May 8-10) in San Francisco! I’ll be speaking/co-presenting with some fantastic presenters about microservices, service mesh, Istio, serverless, an...
Burr Sutter (@burrsutter) and I (@christianposta) have finished writing a small book to help folks get up and running with Istio.io service mesh!
I see lots of customers moving to microservices, (whether they should or not is a topic for a different post), and in doing so they are attempting to solve some difficult organizational scaling problems. The deta...
Microservices allow us to go faster and reduce our time to value. However, we cannot just naively move fast and break things. We need a way to reduce the risk of making changes and in doing so, make it safer to b...
We’ve been talking about Istio and service mesh recently (follow along @christianposta for the latest) but one aspect of Istio can be glossed over. One of the most important aspects of Istio.io is its ability to ...
When we build services architectures (Service Oriented Architecture, Microservices, the next incarnation, etc), we end up making a lot more calls over the network. The network is perilous. We try to build redunda...
Just getting back from KubeCon 2017 and I can tell you the excitement about Istio and service mesh in general is through the roof! There were lots of talks about Istio/service mesh (including a panel with Matt Kl...
In the first part (part I) we introduced a strategy to bring microservices to our architecture without disrupting the current request flows and business value by looking at a concrete example. In the second part,...
Let’s dive right in! In the previous post (part I) we set up the context for this blog. Basically, as we introduce a strategy to bring microservices to our architecture, we cannot and should not disrupt the curre...
Quick interlude to my last blog. As part of my last blog on low-risk monolith to microservice architecture, I made this statement about microservices and not doing them:
As part of a two-day microservices workshop I’m putting together, I’ve been thinking a lot about how to explain monolith-application decomposition and what a transition to microservices might look like. This is a...
I’ve talked quite a bit recently about the evolution of microservices patterns and how service proxies like Envoy from Lyft can help push the responsibility of resilience, service discovery, routing, metrics coll...
This blog is part of a series looking deeper at Envoy Proxy and Istio.io and how it enables a more elegant way to connect and manage microservices. Follow me @christianposta to stay up with these blog post rele...
Continuing on with my series about microservices implementations (see “Why Microservices Should Be Event Driven”, “Three things to make your microservices more resilient”, “Carving the Java EE Monolith: Prefer Ve...
Some of this I cover in my book “Microservices for Java Developers” O’Reilly June 2016 (launching soon!), but I want to give a more specific treatment of it here. I get questions from folks about NetflixOSS (it’s...
One of the advantages of building distributed systems as microservices is the ability of the system as a whole to withstand faults and unexpected failures of components, networks, compute resources, etc. These s...
I just delivered a 4-day deep-dive training course on Docker and Kubernetes to a customer in Atlanta. In true open-source spirit, I’d like to publish the source/slides and allow other people to benefit from it an...
A lot of teams I talk to recently are very interested in “DevOps” (whatever that means… seems to mean different things to different people?) and when we sit down and talk about what that really means, the directi...
