AWS, or Amazon Web Services, is an online platform that offers scalable and cost-effective cloud computing solutions. As we can see, since AWS services were created in 2002, they have made significant contributions to the globe, as seen by the fact that in 2019, AWS released about 100 cloud services. AWS recorded $14.8 billion in net revenue in the second quarter of 2021, putting it ahead of competing cloud computing platforms like Microsoft Azure. AWS has considerably surpassed its competitors in terms of size and presence in the computing world. According to one independent analysis, AWS holds over a third of the market (32.4 percent), followed by Azure (20 percent), and Google Cloud (9 percent) in the first quarter of 2021.
I've already seen ten AWS modules that have given me a thorough understanding of how AWS works. From module 1, I can define the AWS (Amazon Web Services) is Amazon's complete cloud computing platform, which comprises infrastructure as a service (IaaS), platform as a service (PaaS), and packaged software as a service (SaaS) product. I also learned that AWS pricing philosophy offers a pay-as-you-go pricing model for over 200 cloud services in module 2. In module 3, I can identify there are four global components of AWS and that is availability zones, region, edge locations and regional edge caches. The global infrastructure is built to help the customers to achieve lower latency and higher throughput, and to ensure that their data resides only in the AWS Region they specify. In module 4, I learned on how to secure my workloads and applications in the cloud as AWS provides you a data protection as AWS offers services to help you safeguard your data, accounts, and workloads from illegal access. AWS data security services monitor protects your accounts and workloads by encrypting and managing keys, as well as detecting threats. I also was able to create an AWS Virtual Private Cloud and demonstrate when to use Amazon Elastic Compute Cloud (EC2), AWS Lambda and AWS Elastic Beanstalk by watching the video given in AWS module 5 and 6. From module 7, I can differentiate between Amazon S3, Amazon EBS, Amazon EFS and Amazon S3 Glacier by comparing these based on characteristics for storage type, accessibility, availability, durability, size of data, usability, pricing, scalability to its users, performance and geographic interchangeability. The Well-Architected framework was created to aid cloud architects in the creation of the most secure, high-performing, resilient, and efficient infrastructure for their applications. This framework gives customers and partners a uniform way to analyse architectures, as well as direction on how to develop designs that will grow with your application's needs over time in module 9. Security, dependability, performance efficiency, cost optimization, and operational excellence are the five pillars of the AWS Well-Architected Framework. Lastly, I watched the module 10 video which explain about Elastic Load Balancing (ELB), Amazon CloudWatch, and Auto Scaling. For Amazon Web Services (AWS) installations, Elastic Load Balancing (ELB) is a load-balancing service. ELB distributes incoming application traffic automatically and scales resources to suit demand. An IT team can use ELB to change capacity based on incoming application and network traffic. Meanwhile, CloudWatch collects monitoring and operational data in the form of logs, metrics, and events, and visualizes it using automated dashboards so you can get a unified view of your AWS resources, applications, and services that run on AWS and on premises. AWS Auto Scaling continuously analyses your applications and adjusts capacity as needed to ensure consistent, predictable performance at the lowest feasible cost. AWS Auto Scaling simplifies scaling by providing recommendations that help you maximise performance, costs, or a combination of the two.
