In 2017, we saw the rise and eventual takeover of the container orchestration tool, Kubernetes. Although a lot of great alternatives exist such as Docker Swarm, Mesos and Amazon ECS, Kubernetes became the leader for running containers at scale. Its benefits are that it’s Cloud native (it was designed to run applications at scale on Cloud platforms) and the ability to provide a virtual abstraction layer on top of Cloud providers enabling users to deploy their applications consistently between Cloud providers.
Last November, a good friend of ours, Paul Dix from InfluxData, invited me along to their InfluxDays summit in San Francisco. (Sidenote: Our very own David Cromberge will be presenting at InfluxDays summit in New York next month on why NOT to build your own time-series database and our evolving architecture behind the scenes)
We kicked off our first DevOps Exchange meetup of 2018 this month, with some excelent talks from Docker, Paddy Power Betfair and Motion Picture Solutions. We also announced the new Slack Channel we've launched to help connect the community in between our meetups. You can sign up here:
Also don't forget to help us complete our State of DevOps Monitoring Survey 2018 - we really need your help to make it successful and will be presenting the results back to the whole community later on!
Our November DOXLON only had a couple of talks this month, both focusing on the culture and success of DevOps in two London organisations, Reevoo and HSBC. However our vertain speakers (who've spoken at DOXLON in the past) really managed to fill up the extra time with some great stories and insights on how they implemented DevOps in their organisations.
Tell me if this sounds familiar. Your users are complaining about the performance of a Java application in production, so you take a quick look at CPU and memory usage on the host. Both are fine. You dig a little deeper with tools like ps, nmon, sar, and iostat. Still nothing terribly wrong. With a sinking feeling, you realize the problem lies somewhere inside the JVM. What do you do now?
Our October DOXLON featured a solid DevOps Exchange line up, covering some very current topics in the DevOps world. We started with Rob Elkin, CTO @ Busuu talking about Serverless, then Matthew Macdonald-Wallace, a seasoned DevOps consultant ranting about how DevOps has been hijacked by marketing and sales teams, and last but not least, Connon MacRae, VP TechOps at Ticketmaster, talking about their journey to DevOps.
Although this started out as a general DevOps meetup for September, after our call for speakers it turned out that everyone wanted to talk about Kubernetes! Kubernetes deployments, Kubernetes Networking and Kubernetes storage. This was my first DOXSFO after being away all summer in London and reconnecting with our original meetup we started there, DOXLON, and it was great to see how far our San Francisco meetup has come along since I last attended!
Our August DOXLON featured a solid DevOps Exchange line up, covering some very current topics in the DevOps world. We started with Owain Perry and his monitoring solutions at Just Eat. Following Richard Clark took us through how to build a resilient VPC transit network. We closed with Graeme Forbes on the topic of SSL.
Glad to be back in San Francisco for another DOXSFO event. We were fortunate to have four awesome speakers this time around on the topic of Continuous Integration. We started with Chloe Condon who spoke about why you need to stop using “the” staging server. Following that we had Amit Mishra and Kashyap Parikh gave us interesting insight on how GitHub combined with CI empowers rapid product delivery at Credit Karma. We closed out the evening with Edith Harbaugh and learned how and when to feature flag.
By now, the advantages of microservices—like more agility, modularity, scalability, reliability and so on, are probably familiar to you. But like all new technologies, microservices present new challenges in addition to new benefits.
