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)

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...

Essential Cloud Computing Characteristics

If you ask five different experts you will get maybe five different opinions what cloud computing is. And all five may be correct. The best definition of cloud computing that I have ever found is the National Institute of Standards and Technology Definition of Cloud Computing. According to NIST the cloud model is composed of five essential characteristics, three service models, and four deployment models. In this post I will look at the essential characteristics only, and compare to the traditional computing models; in future posts I will look at the service and deployment models... (more)

The Importance of Private Clouds

Few days ago I noticed a question on a LinkedIn group that made me thinking how important is the notion of private clouds. First, let's briefly look at what is the difference between public, private and community clouds as well as hybrid clouds. Once again those are very well defined in NIST Definition of Cloud Computing but stated with simple words they are: Private Cloud is cloud infrastructure that belong to single organization (enterprise, university, government organization etc.) that is hosted either on or off premise and is managed by the organization or third party contr...
