Microsoft LEAP: Accelerating Business Value

This is my third article from Microsoft LEAP and todays’ focus is the use of microservices and Kubernetes.

Containers Are Crucial For the More Essential Microservices

A very important topic that was discussed throughout the agenda of the conference was the use of Microservices and how essential they are for most applications for the business sectors. With different approaches and angles to this topic, Brendand Buns, one of Kubernetes co-founder, gave a session which focused on the use of containers for microservices. He focused on his product, Kubernetes, which is one of the best and most recommended open-source services for the use containers with the use of policies. Microservices are important due to their ability of being agile and their sophisticated architecture which helps in a faster digital offering.

However, currently found microservices are used on physical services which leads to many problems. This is why the use of containers is a breakthrough which gives the user a light runtime environment. It can also be used on physical or virtual servers which is a huge development compare to older technologies.

The use of containers will also help in providing better isolation, due to the use of many executions on only one operating system. Such an opportunity will aid developers in minimizing the use of many different VMs. Brendand discussed the use of Domain driven developments against using test driven developments; in terms the more relatable for businesses and how to pick the right method. Overall, the final conclusion was to reflect the scaling levels that could be reached through using Kubernetes as a service to provide containers while using microservices for your business.

The Use of Service Fabric Mesh

One popular session in the program was by Mark Fussell and Vaclav Turecek. This talk discussed the introduction of the anticipated future product called Service Fabric Mesh, with a full comparison with the currently used cloud service. Many different points have been discussed to describe the service fabric fully. However, the audience got more excited when they heard the different benefits that are met while using this new service.

Mark spoke about the time taken to create instances of VMs and the hassle in the whole process. This is where service fabric shines as it creates the VMs only once, allowing it to be used through the platform. More packages can be added to the cluster further on without any time consumptions. The second point tackled by Vaclav was the hosting opportunities with service fabric which is described as high-density. Which explains why the cost is lower for service fabrics, as the applications are not connected to the VMs in particular, giving a space to connect more than one application to a single VM.

Last but not least, they both discussed the flexibility of the service fabric mesh to be used with different servers or any different environments, disregarding the current existing infrastructure. They added the fact that service fabric helps in controlling the machine lifecycle. Developers were more educated on the differences between cloud technologies and whether to transfer or not.

The Touch Point: ACI and AKS

When it comes to the use of Azure Container Instances(ACI), Justin Luk, the product manager for Azure and Kuberentes, was the best pick for such content. Developers were glad to know that containers by AKS can be used with their ACIs. The containers can be quickly used when needed without any preps, saving time and effort. Instances will also be easily deleted directly after the needed work is done. AKS is used in these on-demand moments to monitor the work and control the creation and deletion process. This can help developers provide new severs instantly when needed without any hassle. When a certain problem or demand is asked for, AKS are used to reach the needed output without any extra services or products.

An Environment of AKS: Best Practices

Another session that stood out from all the Kubernetes sessions was the one conducted by Saurya Das, another product manager in Azure. This session was to reflect the success stories by some of the developers out there that used AKS in their platforms. Developers were happy to know about the multi-tenancy when using the cluster isolation. In addition, was the different network designs that could be used with their new service. These networks can also be implemented using policies, that help make the development easier and more secure. Overall, everyone in the session was satisfied to know about the scaling opportunities to expect and the strong control for monitoring and handling it possesses.

On the other hand, Ralph Squillace, gave a wider image and a better understanding on multi-tenancy and their use with AKS. He discussed how it is commonly mistakenly used through the AKS products itself, whereas it is actually recommended to be used in the application directly. Ralph emphasized on such points, by relating to some best practices which were mainly of SaaS products. He gave a few tips and tricks on how your service should be in terms of security, designs, policies and much more in order to be able to integrate and handle the multi-tenancy directly and easily through the application.

Kubernetes: Guide for its Tools

The end of this section of containers being used was bent towards introducing the different operating tools that will assess developers while using kubernetes services. Bridget Kromhout was able to introduce the developers to new tools as Terraform, Helm, Draft, Brigade, Kashti and many others. These different tools were discussed thoroughly on how to use them in terms of configurations and app development. They were also helpful in scripting for event-driven operations and to manage the app fully. Developers were happy to learn how to efficiently use Kubernetes and containers for their currently existing architectures and structures.

All in all, a very on-topic and interesting day at Micrososft LEAP 2019. I look forward to the next sessions. If you have any questions, feel free to contact me at bjorn.nostdahl@nostdahl.com
