Architecting Backup Infrastructure for Dynamic Workloads in the Cloud Recently I had to design the backup infrastructure for cloud workloads for a client in order to ensure that we comply with the Business Continuity and Disaster Recovery standards they have set. However, following traditional IT practices in the cloud quite often poses certain challenges. The scenario that we had to satisfy is best shown in the picture below: The picture is quite simple: Application servers have a backup agent installed The backup agent submits the data that needs to be backed up to the media server in the cloud The cloud media server submits the data to the backup infrastructure on premise, where the backups are stored on long-term storage according to the policy This is a very standard architecture for many of the current backup tools and technologies. Some of the specifics in the... (more)

CI/CD Pipelines | @DevOpsSummit #AI #ML #CI #CD #DevOps #Monitoring

For a while already we have been working with a large enterprise client, helping them to migrate their on-premise workloads to the cloud. Of course, as added value to the process, they are also migrating their legacy development processes to the modern, better, agile DevOps approach. And of course, they have built a modern Continuous Integration/Continuous Delivery (CI/CD) pipeline consisting of Bitbucket, Jenkins, Artifactory, Puppet and some relevant testing frameworks. “It is all great!”, you would say “what is the problem?”. Because I am on all kinds of mailing lists for thi... (more)

AWS Outage and High Availability | @DevOpsSummit #SDN #AWS #Monitoring

After yet another cloud outage yesterday (see AWS’s S3 outage was so bad Amazon couldn’t get into its own dashboard to warn the world) the world (or at least its North American part) once again went crazy how dangerous the cloud is and how you should go build your own data center because you know better what is good for your business. Putting aside all the hype as well as some quite senseless social media posts about AWS SLAs, here is our thought process for developing highly available cloud services or more importantly making conscious decisions what our services’ SLAs should b...

Are There Other "as-a-Service" Cloud Offerings?

As already described in the previous few articles NIST defines three different service models for the cloud - IaaS, PaaS and SaaS. However if you look at the Wikipedia article about cloud computing you will notice that there are quite a few more "as-a-service" models mentioned there. Lot of vendors are using those to differentiate their offerings but there are two problems that arise: First, those additional models are not officially recognized by any standardization authority and Second, and maybe more important, those new acronyms add to the confusion among the novice cloud us...

Is Your Cloud Ready for the Enterprise?

Reading my newsfeed this morning I noticed several articles talking about the cloud and the enterprise. There is no doubt that the area is heating up with more and more acquisitions (IBM buys Softlayer), investments (GE invests $105M in Pivotal) and fights over big deals (IBM vs. AWS for the CIA cloud) but the question that comes up is: "Are the cloud platforms ready for the enterprise?" Being involved with numerous cloud projects I see five areas that enterprises emphasize when they evaluate their options. Those are not too different from the criteria they use for any other sof...
