The networking industry has a somewhat unique relationship with high availability. For compute, storage, and applications, failures are somewhat tolerable because they tend to be more isolated (a single server going down rarely impacts the rest of the servers).
Have you moved your Hadoop jobs over to Yarn? Are you seeing the following NullPointerException coming out of your job?
A serious vulnerability, being eferred to as Shellshock, was just reported in the Bourne-Again Shell (bash) that affects most *NIX-based systems. Halo users can quickly find out which servers have this vulnerability present using the newly-released Reports page in your Halo portal, or using the Halo API.
Last but not least in my series of four videos from the Cloud Standards Customer Council is an interview with Bernard Golden. Bernard, who is the VP of strategy at ActiveState, provided an industry perspective talk entitled: What Should PaaS Standards Look Like.
Brian talks with Alex Polvi (@polvi, CEO of @CoreOSLinux) about the evolution of CoreOS over the past year, and the breadth of products and services (etcd, systemd, fleet, Docker, Flannel) that have been built to integrate and augment CoreOS.
Make sure you didn't miss anything with this list of the Best of the Week in the Cloud Zone (Sept 19 to Sept 25). This week's topics include the post IaaS world, NCDevCon session summaries, Google Compute quickstart tutorials, how eBay uses OpenStack Trove, and the future of PaaS & Docker.
There are always a few objections that come up as well. Following-up on a previous blog post where we discussed the business benefits of cloud computing, this will be a discussion on the most common objections and how to have a conversation around cloud and on-premise environments.
The hype says that Shellshock is in the same league as Heartbleed. But in all seriousness, it does have the potential to be a biggie, so I wanted to put together something definitive both for me to get to grips with the situation and for others to dissect the hype from the true underlying risk.
On this episode of the Cloudcast, Aaron & Brian talk with Manoj Chaudhary (CTO & VP of Engineering @loggly) about building and managing massively scalable SaaS applications.
How to do blue-green deployment with CloudFoundry.
I came across a conference video starring Auston McReynolds and Mat Lowery, both software engineers at eBay, who go on to describe the use and role of OpenStack Trove in eBay's process. They cover the creation of eBay's OpenStack cloud and using Trove throughout the company.
In Part 1 of this article, we’ll cover NoSQL databases, differences between relational databases, designing, and creating your Azure Table. In Part 2, we’ll cover writing queries to our tables, retrying failed operations, concurrency, and of course security.
APM solutions give you great visibility into any code you have control over; however, today’s systems are largely a combination of code you write along with off-the-shelf components, sitting on top of VMs/containers, and cloud-based services.
One of the core data structures provided by Hazelcast is IMap extendingjava.util.concurrent.ConcurrentMap - which is basically a distributed map, often used as cache
OpenStack Heat makes orchestrating the deployment of multiple elements a breeze using its stack concept. I will explain as well as show a live example of one aspect of the integration that lets Cloudify import the Heat stack and build a Cloudify blueprint (that is TOSCA inspired) on top of it.
This is a quickstart tutorial for getting started with Google Compute Engine: namely how to create an instance and install Apache web server. It's a pretty basic point for getting started, but definitely necessary, and includes a lot of great documentation on Google's behalf.
At last week’s Cloud Standards Customer Council held in Austin Texas, the first panel of the day dealt with “Current and Future PaaS Trends.” The panel debated whether there should or could be a PaaS standard as well as what its future might look like.
The point is that the real conversation is not about open but about something more precise. Without that precision (the business objective behind the request), the discussion isn’t terribly meaningful.
The simplest way to overcome this issue from the operator’s point of view is to use only one writer node for these types of transactions. This usually involves configuration change at the load-balancer level. See this post for possible load-balancer configurations.
Recently we combined the Citrix Cloud Platforms Group and the Citrix Cloud Networking Group into one integrated unit called Citrix NCSP (Networking, Cloud & SP Group). We believe these changes will strengthen our position in the quickly evolving data center market.
Make sure you didn't miss anything with this list of the Best of the Week in the Cloud Zone (Sept 5 to Sept 12). This week's topics include workflow automation, an OpenStack MySQL perspective, multi-tenant cloud platforms and virtualization, networking Docker containers, and scaling Azure sites.
Today I attended a day-long event put on here in Austin by the Cloud Standards Customer Council. It was a packed agenda focused around the theme “preparing for the post-IaaS phase of cloud adoption.”
DZone curators and research analysts recently attended NCDevCon, an annual event for web and mobile developers in Raleigh, NC. This article includes videos from a number of sessions they found interesting, as well as a link to the total video sessions from the conference.
An interesting (and informative!) video has come out of the recent DockerCon Hackathon. The video elaborates on how to manage Docker containers with ElectricCommander and demonstrates what the pipeline for that process is going to look like.
Moving from a traditional monolithic architecture to a microservices approach is an enormous change for any organization, and fraught with multiple challenges. I'll cover a number of these here, including an emphasis on a microservices approach that isn't to be taken lightly.
