OpenStack storage is probably one of the most complex topics in OpenStack architecture right after networking. There are many different storage options, at least a few storage services, and tons of supported storage backends. It is very easy to get lost. But do not worry, there is hope. Since OpenStack was initially created as an open-source implementation of the Amazon Web Service Elastic Compute Cloud (AWS EC2), its storage architecture is quite similar to leading public clouds.

After becoming increasingly popular in the mid-2000s, cloud computing has revolutionized the data center industry. Aside from providing cost-savings, security, mobility, and scalability benefits, cloud computing was also expected to be more environmentally friendly than other data storing and processing methods. By being highly efficient, cloud operators can reduce the use of electricity and other materials that typically increase a data center’s carbon footprint.

Avoid Writing a Lot of Try Catch by Catching The ‘catch()’ Just Once. How annoying it is to write a lot of try-catch for each async function in an express app? What if you never need to write a try catch block for all async functions and still be able to handle the errors?

Dedicated hosts for macOS are now available on CircleCI. This new layer of support is built exclusively for macOS and offers Apple developers unprecedented storage, security, and scalability on CircleCI. By reserving a dedicated host, teams can unlock access to a bare metal instance that provides exclusive access to an entire host machine for 24 hours.

“End of life, end of support, pandemic-induced shipping delays and remote work, scanning failures: It’s a recipe for a patching nightmare.”, federal cybersecurity CTO Matt Keller says. Ensuring a high level of security for your IT infrastructure and being sure you have not missed something is hard to arrange during these days. A zero-day exploit happens when hackers identify a software weakness or a security gap and take advantage of it to perform a cyberattack.

Developers love containers for their portability and flexibility. Suitable for today’s cloud-native environment and agile development requirements, containers make it super-fast to develop, test, and run applications. Besides this, they are lightweight and can optimize the platform (and the host OS) they are deployed on. Now, for powerful applications with hundreds of containers, the platform should also be portable, flexible, extensible, and efficient.

Mattermost v6.4 is generally available today and includes the following new features (see changelog for more details).
