Developers running their apps on tsuru can choose plans based on memory and cpu usage. We were looking at adding I/O usage as one of the plan’s features, so one could choose how many I/O operations per second or bytes per second a container may be able to read/write. Being able to limit I/O is particulary important…
tl;dr “Transparent Hugepages” is a Linux kernel feature intended to improve performance by making more efficient use of your processor’s memory-mapping hardware. It is enabled ("enabled=always") by default in most Linux distributions. Transparent Hugepages gives some applications a small performance improvement (~ 10%…
I’m using Golang for a while. During the development, I was used to repeatedly execute “go build”,“go test” manually. This was a bad habit on which I resign. It is not so painful if you use simple command without any args. But in case of more complex tasks, naturally, it is going to be a…

Lessons learned in scaling out the PostgreSQL database in the cloud using Citus, an open source extension to Postgres that is also available as a fully-managed database as a service. From operational pain points like HA to disaster recovery to backups to monitoring and logging and alerts.
On September 14, 2016 we announced Envoy, our L7 proxy and communication bus. In a nutshell, Envoy is a “service mesh” substrate that…
As a programming father you need to be concerned about your budget. This means resisting the temptation to buy the most amazing hardware, an...
A multi-cloud strategy can help organizations leverage strengths of different cloud providers and spread critical workloads. For example, maybe you have an existing application on AWS but want to use Google’s powerful APIs for Vision , Cloud Video Intelligence and Data Loss Prevention , or its big data and machine…
The first GCP region in India is now open for you to build applications and store your data.
The previous article Docker in Production: A History of Failure was quite a hit. After long discussions, hundreds of feedbacks, thousands of comments, meetings with various individuals and major pl…
We take a look at the performance of our 86,529 hard drives and break down the failure rates by manufacturer and model size.
No single cloud fits all. Explore how we build a more flexible future with hybrid cloud.
Serverless architecture is a cloud-based development model in which the cloud provider manages the servers and the developer only needs to focus on the code.
Monitor agents, cron jobs, websites, APIs, and everything in between. Jobs, uptime checks, heartbeats, status pages and analytics in one tool.
Any containerized application typically consists of multiple containers. There are containers for the application itself, a database, possibly a web server, and so on. During development, it’s normal to build and test this multi-container application on a single host. This approach works fine during early dev and test…
Editor’s note: Today’s guest post is by Jeff McCormick, a developer at Crunchy Data, showing how to build a PostgreSQL cluster using the new Kubernetes StatefulSet feature. In an earlier post, I described how to deploy a PostgreSQL cluster using Helm, a Kubernetes package manager. The following example provides the…
We’re excited to announce the beta release of managed SSL certificates at no charge for applications built on Google App Engine . This service automatically encrypts server-to-client communication — an essential part of safeguarding sensitive information over the web. Manually managing SSL certificates to ensure a…
Ever since the first EC2 instances launched — the ones which were retrospectively named "m1.small" — Amazon has relied on the Xen hypervisor. No longer: C5 instances use KVM. This sounds like it would be a problem, but in fact that change didn't bother FreeBSD at all: Now that everything uses hardware-based paging…
