Which AWS service provides a simple and scalable shared file storage solution for use with Linux based?

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 compute, 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 compute, databases, infrastructure management, application development and security. These services, by category, include the following:

• compute
• storage
• databases
• data management
• migration
• hybrid cloud
• networking
• development tools
• management
• monitoring
• security
• governance
• big data management
• analytics
• artificial intelligence (AI)
• mobile development
• messages and notification

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 compute 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 includes various tools and services designed to help users migrate applications, databases, servers and data onto its public cloud. The AWS Migration Hub provides a location to monitor and manage migrations from on premises to the cloud. Once in the cloud, EC2 Simple Systems Manager helps an IT team configure on-premises servers and AWS instances.

Amazon also has partnerships with several technology vendors that ease hybrid cloud deployments. VMware Cloud on AWS brings software-defined data center technology from VMware to the AWS cloud. Red Hat Enterprise Linux for Amazon EC2 is the product of another partnership, extending Red Hat's operating system to the AWS cloud.

Once applications, databases, servers and data are migrated to the cloud or a hybrid environment, tools like AWS Outposts deliver AWS services and infrastructure across multiple environments.

Networking

An Amazon Virtual Private Cloud (Amazon VPC) gives an administrator control over a virtual network to use an isolated section of the AWS cloud. AWS automatically provisions new resources within a VPC for extra protection.

Admins can balance network traffic with the Elastic Load Balancing service, which includes the Application Load Balancer and Network Load Balancer. AWS also provides a domain name system called Amazon Route 53 that routes end users to applications.

An IT professional can establish a dedicated connection from an on-premises data center to the AWS cloud via AWS Direct Connect.

Developer tools

A developer can take advantage of AWS command-line tools and software development kits (SDKs) like AWS CloudShell to deploy and manage applications and services:

• AWS Command Line Interface, which is Amazon's proprietary code interface;
• AWS Tools for PowerShell, which developers use to manage cloud services from Mac, Windows and Linux environments.
• AWS Serverless Application Model, which developers use to simulate an AWS environment to test functions of AWS Lambda, a compute service that lets developers run code from over 200 AWS services and SaaS applications.

AWS SDKs are available for a variety of platforms and programming languages, including Android, C++, iOS, Java, Node.js, PHP, Python and Ruby.

Amazon API Gateway lets a development team create, manage and monitor custom application programming interfaces (APIs) that let applications access data or functionality from back-end services. API Gateway manages thousands of concurrent API calls at once.

AWS also provides Amazon Elastic Transcoder, a packaged media transcoding service, and AWS Step Functions, a service that visualizes workflows for microservices-based applications.

A development team can also create continuous integration and continuous delivery pipelines with the following services:

A developer can store code in Git repositories with AWS CodeCommit and evaluate the performance of microservices-based applications with AWS X-Ray.

AWS also offers machine learning (ML) services for developers:

• AWS CodeWhisperer, which provides code recommendations to developers based on prior code they've used;
• AWS CodeArtifact, a development paradigm for building ML models; and
• Amazon SageMaker, a fully managed service that helps developers and data scientists build and deploy ML models.

Management and monitoring

An admin can manage and track cloud resource configuration using AWS Config and AWS Config Rules. Those tools, along with AWS Trusted Advisor, can help an IT team avoid improperly configured and needlessly expensive cloud resource deployments.

AWS provides several automation tools in its portfolio. An admin can automate infrastructure provisioning via AWS CloudFormation templates, and also use AWS OpsWorks for Chef to automate infrastructure and system configurations.

An AWS customer can monitor resource and application health with Amazon CloudWatch and the AWS Personal Health Dashboard. Customers can also use AWS CloudTrail to retain user activity and API calls for auditing, which has some key differences from AWS Config.

Security and governance

AWS provides a range of services for cloud security, including AWS Identity and Access Management, which lets admins define and manage user access to resources. An admin can also create a user directory with Amazon Cloud Directory or connect cloud resources to an existing Microsoft Active Directory with the AWS Directory Service. Additionally, the AWS Organizations service lets a business establish and manage policies for multiple AWS accounts.

Amazon Web Services has also introduced tools that automatically assess potential security risks. Amazon Inspector analyzes an AWS environment for vulnerabilities that might impact security and compliance. Amazon Macie uses ML technology to protect sensitive cloud data.

AWS also includes tools and services that provide software- and hardware-based encryption, protect against distributed denial-of-service (DDoS) attacks, acquire secure sockets layer and Transport Layer Security certificates, and filter potentially harmful traffic to web applications.

The AWS Management Console is a browser-based graphical user interface for AWS. It can be used to manage resources in cloud computing and cloud storage as well as security credentials. The AWS Console interfaces with all AWS resources.

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 to 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, its 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:

• DataRow in 2020, a startup that specialized in a web-based client for Amazon Redshift, its cloud data warehouse;
• TSO Logic in 2019, a cloud migration company that provides analytics, letting customers view the state of their data center and model a migration to the cloud;
• CloudEndure in 2019, a company that focuses on workload migrations to the public cloud, disaster recovery and backup; and
• Sqrrl in 2018, a security startup that collects data from points such as gateways, servers and routers and puts those findings inside a security dashboard.
