Azure Tutorials Series - Benefits of cloud computing

-
Now we know what is cloud and why do we use them as already covered in the previous article. We would learn new terminologies in this article related to the cloud.

Benefits of Cloud Computing

Cloud services provides a lot of benefits to its consumers. As an IT consultant you spend a lot of time on the software portal of it instead of going into the hardware. The companies which still uses legacy mainframe systems cannot move to the cloud thinking overnight, I mean the transition needs to be gradual here which is often termed as 'lift and shift'.

Now let's see what are the benefits of cloud computing!

Cost effective
  • Provides Pay-as-you-go or consumption based pricing model.
  • No upfront infrastructure cost
  • Ability to scale up or scale in when needed
  • Usage of Artificial intelligence tools to predict future estimate.
Scalable
  • Ability to increase or decrease the resources or Services based upon workload at any given time
  • 2 terms are related here
    • Scaling up - also called vertical scaling which is the ability to add more resources as per the workload, for example, adding more CPUs or RAMs
    • Scaling out - also called horizontal scaling which is the ability to add more machines or VMs that functions together as one unit.
  • Scaling can be done either manually or automatically, as triggering a utilisation limit.
Elastic
  • Based upon current demand cloud computing system can automatically add or remove resources.
  • Can be customised in such a way that traffic is handled well in peak hours and then can be saturated in terms of cost as well.
Fault Tolerance
  • Let's say if any of the component gets failed, a backup component is ready to takes it place with minimal impact on the service, the term is referred as 'Fault Tolerance', it is carried out using replication of the resources.
Global
  • Selecting the location of the resource or service near to your customers.
  • Geographical presence of the data centres for response time coverage.
Physically and Digitally secure
  • Azure resources or services are well secured physically as well as digitally, none of the employees are allowed to access any of the machines allotted to its customers unless given permission to do so.
  • Data centres are well equipped with security camera and security personnel

Well that covers most of it!

In this article, we will learn about Azure networking concepts such as architecture, microservices, virtual networks, VPNs, subnet, VPN gateways and most importantly Network Security Group(NSG). All these terms are to be understood if you appearing for AZ900 Microsoft Azure Fundamentals exam. Azure Networking In previous articles we have learnt about Micro- services and how they work, these are alos loosely coupled architecture. Some of the features includes Independent components interact with each other with the help of queues Can be updated and deployed independently Highly scalable Supports Asynchronous messaging N-tier Architecture Supports loosely coupled architecture Application divided into multiple tiers such that higher tier can access lower tier but not vice versa Tiers are re-usable and can be updated or replaced easily without any hassle. Three-tier in general Web Tier(front end) Application tier(back end) Data tier(Storage) Virtual Network Isolated network shared by few g

What is a webdriver? A webdriver is a an automation framework that allows executing our tests in different browsers. It also supports headless execution using HtmlUnit driver. What are hooks? @Before and @After are called Hooks, they are used before and after any test scenario. How would you like your automation framework to be designed? How can you use data properties in Test NG framework? Explain Access specifiers? Access modifiers define the visibility of the class. There are four different

Testing in CI/CD

-
If you are part of testing fraternity you would have heard CI/CD numerous times by now. It's the talk of the software testing town. In this article, we will cover the basics of CI/CD, what actually it is and how it is implemented in software testing. What is continuous integration? In simple terms, development teams can integrate their code into a shared repository. This helps in maintaining code quality and identifying potential issues with the local version of the code at an early stage. What is continuous delivery? Everything that is being continuously merged by the development team, is continuously deployed to the live environment. Continuous delivery is often coined as ‘Continuous Deployment’ as well. Since most developers work in parallel, continuously integrating their code into one repository would mean that the master branch is continuously updated with new features. In order to ensure that there is no compromise in the code quality with so many changes
