Microsoft MVP For Sixth Time
I am delighted to announce that I have been awarded Microsoft Most Valuable Professional 2015 award in Microsoft Azure.This is my sixth Microsoft MVP award in a row (2010 - 2015).
Using Azure Event Hubs As A Message Hub For IoT Scenarios
When we build apps for larger IoT scenarios or working on Big Data solutions, one major challenge would be to handle millions of messages received from hundreds of systems where these messages will be subscribed by hundreds of other systems. To handle this kind of problem using our traditional enterprise messaging systems and publish-subscribe message brokers would be really a challenge as we need to handle massive amount of stream of data in a second, in which we may need to process the data and events in near real-time. Our most of the existing publish-subscribe message brokers would be failed when we deal with millions of messages in a second. Technologies like Apache Kafka solves this problem by providing a high-throughput distributed messaging system with a distributed commit log. Kafka is designed for cluster-centric design where you may need to leverage distributed coordination tools such as Apache ZooKeeper for coordinating and synchronizing the cluster nodes. This may leads to lot of operational complexity when working with larger distributed systems.
Building Distributed Cloud Apps With Azure WebSites, WebJobs And Azure Service Bus Topic
In my previous blog post, Building Distributed Cloud Apps With Azure Cloud Services And Azure Service Bus Topic, I have introduced a reference Azure app for developing multi-tiered distributed apps using Azure Cloud services and Azure Service Bus Topic. In that app, we have used two Azure worker roles for running a background processing system and a Notification Hub. This app is same like the previous one, the only difference here is that we are replacing two Azure worker roles with two WebJobs and running in a Azure WebSite. In the previous system, we have used a one Azure web role and two Azure worker roles for an ordr processing demo app. Here we replace these three systems with one WebSite, which is also working as the host for two WebJobs. In short, we replace the worker role with WebJobs. The extra functionality which we have added in this version is the distributed caching with Azure Redis cache.
Building Distributed Cloud Apps With Azure Cloud Services And Azure Service Bus Topic
We have been developing few sample apps for providing guidance on building cloud apps with Microsoft Azure. We release the first sample app for building distributed apps on Microsoft Azure. The guidance app is available on github at https://github.com/AccelNA/azure-guidance.
