When Kappa first appeared as an architecture style (introduced by Jay Kreps) I was really fond of this new approach.
The Azure CLI is my favorite tool to manage Hadoop Clusters on Azure. Why? Because I can use the tools I am used to from Linux now from my Windows PC. In Windows 10, I am using the Ubuntu Bash for that, which gives me all the major tools for managing remote Hadoop Clusters. One thing I am doing frequently, is starting and stopping Hadoop Clusters based on Cloudera. If you are coming from Powershell, this might be rather painfull for you, since you can only start each vm in the cluster sequentially, meaning that a cluster consisting of 10 or more nodes is rather slow to start and might take hours! In the Azure CLI I can easily do this by specifiying “–nowait” and all runs in parallel. The only disadvantage is that I won’t get any notifications on when the cluster is ready. But I am doing this with a simple hack: ssh’ing into the cluster (since I
2016 is around the corner and the question is, what the next year might bring. I’ve added my top 5 predictions that could become relevant for 2016: The Cloud war will intensify. Amazon and Azure will lead the space, followed (with quite some distance) by IBM. Google and Oracle will stay far behind the leading 2+1 Cloud providers. Both Microsoft and Amazon will see significant growth, with Microsoft’s growth being higher, meaning that Microsoft will continue to catch up with Amazon More PaaS Solutions will arrive. All major vendors will provide PaaS solutions on their platform for different use-cases (e.g. Internet of Things). These Solutions will become more industry-specific (e.g. a Solution specific for manufacturing workflows, …) Vendors currently not using the cloud will see declines in their income, as more and more companies move to the cloud Cloud Data Centers will become more often outsourced from the leading providers to local companies, in order to overcome local legislation Big
Amazon announced details about their Q2 earnings yesterday. Their cloud business grew with incredible 81%. This is massive, given the fact that Amazon is already the number #1 company in that area. This quarter, they earned 1.8 billion USD from cloud computing. Summing up this number, their revenue would definitively reach some 7 billion this year. However, if this growth continues to increase so fast, I guess they could even get double-digit by the end of this year. Will Amazon reach 10 billion in 2015? If so, this would be incredible! Microsoft stated that their growth was somewhere well above the 100% mark, so I am interested in where Microsoft will stand by the end of the year. But what does this tell us? Both Microsoft and Amazon are growing fast in this business and we can expect that we will see many more interesting services in the coming month and years in the Cloud. My opinion is that the
