This Week I Learned -
* Azure Reservations helps you save money by pre-paying for one-year or three-years of virtual machine, SQL Database compute capacity, Azure Cosmos DB throughput, or other Azure resources.
* As with other managed disks, Standard SSD is stored in triplicate on Locally-Redundant Storage (LRS). The disks are designed to have 99.999% availability
* Containers are designed to be stateless and changes made to the container are sandboxed and they do not affect the container host. Unlike VMs, containers do not provide hardware virtualization. Instead, they provide virtualization at the operating systems level. Containers share portions of the host operating system kernel which is why Windows containers are limited to Windows hosts and Linux containers can only run on Linux hosts. However, recent changes in Windows Server container support include using a small specialized Linux VM to enable the running of Linux containers on Windows hosts. A container host can be a VM or it can be a physical system - Petri
* Docker and Kubernetes are different, but not rivals...Kubernetes can be integrated with the Docker engine to carry out the scheduling and execution of Docker containers. As Docker and Kubernetes are both container orchestrators, both can help to manage .. containers and also help in DevOps implementation. Both can automate most of the tasks that are involved in running containerized infrastructure and are open source software projects, governed by an Apache License 2.0. Apart from this, both use YAML – formatted files to govern how the tools orchestrate container clusters.
* The GCP Professional Cloud Architect certification exam curriculum is changing from November 9, 2018 onwards. See the changes (generated using Copyscape) between the new & old curriculum
* Pivotal offers many useful free & complimentary ebooks:
Modernizing .NET Applications
Thinking Architecturally
Building Microservices with ASP.NET Core
Beyond the 12 Factor App
* The most startling fact about 2002 is that the combined profits for the ten drug companies in the Fortune 500 ($35.9 billion) were more than the profits for all the other 490 businesses put together ($33.7 billion) - NY Times
* India is set to touch 1 billion in debit cards including 560 million RuPay cards (introduced in 2012)
