1. AWS

2. Introduction AWS launched in 2006 from the internal infrastructure that Amazon.com built to handle its online retail operations. 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 u needed. Amazon Web Services provides services from dozens of data centres spread across availability zones (AZs) in regions across the world. An AZ represents a location that typically contains multiple physical data centres, while a region is a collection of AZs in geographic proximity connected by low-latency network links.

3. Why does Amazon care about Scientific Computing? In order to fundamentally accelerate the pace of scientific discovery. It is a great application of AWS with a broad customer base The scientific community helps us innovate on behalf of all customers ◦ Streaming data processing & analytics ◦ Exabyte scale data management solutions and scale compute ◦ Collaborative research tools and techniques ◦ New AWS regions

4. Types of Cloud Computing Cloud computing is providing developers and IT departments with the ability to focus on what matters most and avoid undifferentiated work like procurement, maintenance, and capacity planning. As cloud computing has grown in popularity, several different models and deployment strategies have emerged to help meet specific needs of different users. Infrastructure as a Service (IaaS): Infrastructure as a Service, sometimes abbreviated as IaaS, contains the basic building blocks for cloud IT and typically provide access to networking features, computers (virtual or on dedicated hardware), and data storage space.

5. Platform as a Service (PaaS): Platforms as a service remove the need for organizations to manage the underlying infrastructure (usually hardware and operating systems) and allow you to focus on the deployment and management of your applications. This helps you be more efficient as you don’t need to worry about resource procurement, capacity planning, software maintenance, patching, or any of the other undifferentiated heavy lifting involved in running your application. Software as a Service (SaaS): Software as a Service provides you with a completed product that is run and managed by the service provider. In most cases, people referring to Software as a Service are referring to end- user applications.

6. Cloud: A cloud-based application is fully deployed in the cloud and all parts of the application run in the cloud. Applications in the cloud have either been created in the cloud or have been migrated from an existing infrastructure to take advantage of the benefits of cloud computing. Hybrid: A hybrid deployment is a way to connect infrastructure and applications between cloud-based resources and existing resources that are not located in the cloud. The most common method of hybrid deployment is between the cloud and existing on-premises infrastructure to extend, and grow, an organization's infrastructure into the cloud while connecting cloud resources to internal system.

7. Benefits at a Glance Easy to use, Flexible, Cost-Effective, Reliable, Scalable and High Performance, Secure. Easy to Use: AWS is designed to allow application providers, ISVs, and vendors to quickly and securely host your applications – whether an existing application or a new SaaS-based application.

8. Flexible: AWS enables you to select the operating system, programming language, web application platform, database, and other services you need. With AWS, you receive a virtual environment that lets you load the software and services your application requires. This eases the migration process for existing applications while preserving options for building new solutions. Cost-Effective: You pay only for the compute power, storage, and other resources you use, with no long-term contracts or up-front commitments. For more information on comparing the costs of other hosting alternatives with AWS, see the AWS Economics Center.

9. Reliable: With AWS, you take advantage of a scalable, reliable, and secure global computing infrastructure, the virtual backbone of Amazon.com multi-billion dollar online business that has been honed for over a decade. Scalable and high-performance: Using AWS tools, Auto Scaling, and Elastic Load Balancing, your application can scale up or down based on demand. Backed by Amazon’s massive infrastructure, you have access to compute and storage resources when you need them. Secure: AWS utilizes an end-to-end approach to secure and harden our infrastructure, including physical, operational, and software measures.

10. Agility and Instant Elasticity AWS provides a massive global cloud infrastructure that allows you to quickly innovate, experiment and iterate. Instead of waiting weeks or months for hardware, you can instantly deploy new applications, instantly scale up as your workload grows, and instantly scale down based on demand. Whether you need one virtual server or thousands, whether you need them for a few hours or 24/7, you still only pay for what you use. AWS Quick Start reference deployments help you rapidly deploy fully functional software on the AWS Cloud, following AWS best practices for security and availability.

11. Networking An Amazon Virtual Private Cloud (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 AWS load balancing tools, including Application Load Balancer and Network Load Balancer. AWS also provides a domain name system called Amazon Route53 that routes end users to applications. An IT professional can establish a dedicated connection from an on-premises data centre to the AWS cloud via AWS Direct connection.

12. Security, governance AWS provides a range of services for cloud security, including AWS Identity and Access Management (IAM), which allows admins to 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, AWS Organizations enables a business to establish and manage policies for multiple AWS accounts. The cloud provider has also introduced tools that automatically assess potential security risks. Amazon Inspector analyses an AWS environment for vulnerabilities that might impact security and compliance.

13. Solutions The AWS cloud computing platform provides the flexibility to launch your application regardless of your use case or industry. Solution by Application: The AWS cloud computing platform provides the flexibility to launch your application regardless of your use case or industry. Websites, Backup & Restore, Archiving, DevOps, Mobile Services.
