Amazon Web Services (AWS)
What is AWS?
AWS (Amazon Web Services) is a comprehensive, evolving?cloud computing ?platform provided by Amazon that includes a mixture of infrastructure-as-a-service (IaaS ), platform-as-a-service (PaaS ), and packaged-software-as-a-service (SaaS ) offerings. AWS services can offer an organization tools such as compute power, database storage, and content delivery services.
Amazon.com Web Services launched its first web services in 2002 from the internal infrastructure that Amazon.com built to handle its online retail operations. In 2006, it began offering its defining IaaS services. AWS was one of the first companies to introduce a?pay-as-you-go ?cloud computing model that?scales ?to provide users with computing, storage, or throughput as needed.
AWS offers many different tools and solutions for enterprises and software developers that can be used in data centers in up to 190 countries. Groups such as government agencies, education institutions, non-profits, and private organizations can use AWS services.
How AWS works
AWS is separated into different services; each can be?configured ?in different ways based on the user's needs. Users can see configuration options and individual server maps for an AWS service.

More than 200 services comprise the AWS portfolio, including those for computing, databases, infrastructure management, application development, and security. These services, by category, include the following:
Availability
AWS provides services from dozens of data centers spread across 87 availability zones (AZs ) in regions across the world. An AZ is a location that contains multiple physical data centers. A region is a collection of AZs in geographic proximity connected by low-latency ?network links.
A business will choose one or multiple AZs for a variety of reasons, such as compliance, proximity to end customers, and availability optimization. For example, an AWS customer can spin up virtual machines (VMs ) and replicate data in different AZs to achieve a highly reliable cloud infrastructure that is resistant to failures of individual servers or an entire data center.
Amazon Elastic Compute Cloud (EC2 ) is a service that provides virtual servers – called?EC2 instances ?-- for computing capacity. The EC2 service?offers dozens of instance types ?with varying capacities and sizes. These are tailored to specific workload types and applications, such as memory-intensive and accelerated-computing jobs. AWS also provides Auto Scaling, a tool to dynamically scale capacity to maintain instance health and performance.
Storage
Amazon Simple Storage Service (S3 ) provides scalable object storage for data backup, collection, and analytics. An IT professional stores data and files as S3 objects -- which can range up to five gigabytes – inside?S3 buckets ?to keep them organized. A business can save money with S3 through its Infrequent Access storage class or by using?Amazon Glacier ?for long-term?cold storage .
Amazon Elastic Block Store ?provides block-level storage volumes for persistent data storage when using EC2 instances.?Amazon Elastic File System ?offers managed cloud-based file storage.
A business can also migrate data to the cloud via storage transport devices, such as AWS Snowball,?Snowball Edge ,?and Snowmobile, or use?AWS Storage Gateway ?to let on-premises apps access cloud data.
Databases and data management
The?Amazon Relational Database Service ?includes options for Oracle, MariaDB, MySQL, PostgreSQL, SQL Server, and a proprietary high-performance database called?Amazon Aurora . It provides a relational database management system for AWS users. AWS also offers managed?NoSQL ?databases through?Amazon DynamoDB .
An AWS customer can use?Amazon ElastiCache ?and DynamoDB Accelerator as in-memory and real-time data caches for applications.?Amazon Redshift ?offers a data warehouse, which makes it easier for data analysts to perform?business intelligence ?tasks.
Migration and hybrid cloud

AWS pricing models, competition, and customers
AWS's pay-as-you-go model for its cloud services is either on a per-hour or per-second basis. There is also an option to reserve a set amount of compute capacity at a discounted price for customers who prepay or sign up for one- or three-year usage commitments. Customers can get volume-based discounts, meaning the more of a service they use, the less they pay per gigabyte.
The AWS Free Tier is another option. Customers can access up to 60 products and start building on the AWS platform at no cost. Free Tier is offered in three different options: always free, 12 months free, and trials.
Potential customers can use AWS's pricing calculator to estimate expenditures. And AWS-certified third-party experts provide on-demand help to customers in picking a pricing plan.
As of the first quarter of 2022, Amazon AWS?controls 33% ?of the total cloud market, according to Synergy Research Group. This is the most out of any of its competitors, including Microsoft Azure, Google, and IBM in the public IaaS market.

History
The AWS platform was launched in 2002 with a few services. In 2003, it was re-envisioned to make Amazon's compute infrastructure standardized, automated, and web service-focused. This change included the thought of selling access to a?virtual-servers -as-a-service platform. In 2004, the first publicly available AWS service -- Amazon SQS -- was launched.
In 2006, AWS was relaunched to include three services -- Amazon S3, SQS, and EC2 -- officially making AWS a suite of online core services. In 2009, S3 and EC2 were launched in Europe, and the Elastic Block Store and Amazon CloudFront were released and adopted by AWS. In 2013, AWS started offering a certification process in AWS services, and 2018 saw the release of an autoscaling service.
Today AWS offers more than 200 services and has data centers around the world that make it a highly available and scalable platform.
Acquisitions
AWS has acquired multiple organizations. Generally, it hasn't acquired larger well-established companies but, rather, smaller organizations and startups that bolster and improve the cloud vendor's existing offerings. Here are some of its recent acquisitions:
