Introduction to cloud computing with Amazon Web Services – A Guide
Managing the unique and groundbreaking changes in both technology and business over the past decade has created an ongoing IT infrastructure challenge for many senior technology executives. Indeed, over the past ten years, the typical business application architecture has evolved from a desktop-centric installation to client/server solutions and now to web services.
Recently, virtualization has become a widely accepted way to reduce operating costs and increase the reliability of enterprise IT. Along with these technology changes, the speed of innovation and unprecedented acceleration in the introduction of new products has fundamentally changed the way markets work. Along with the wide acceptance of software as a service (SaaS) offerings, these changes have paved the way for the latest IT infrastructure challenge: cloud computing.
What is Cloud Computing?
Cloud computing has become one of the most discussed IT paradigms of recent years. Cloud computing enables organizations to obtain a flexible, secure and cost-effective IT infrastructure, in much the same way that electric grids enable homes and organizations to plug into a centrally managed, efficient and cost-effective energy source. With cloud computing, organizations have the liberty to consume shared computing and storage resources rather than building, operating and improving infrastructure on their own.
Why Cloud Computing?
✓ Flexible: If you are on a business that is growing by the day and has fluctuating bandwidth demands, cloud computing is the ideal solution. Here’s why? With cloud computing, you can scale up or reduce your cloud capacity as and when you deem fit. This by just drawing on the service’s remote servers.
✓ Disaster recovery: Here is a term that’s mandatory for businesses of all sizes. However, for smaller businesses that lack the cash flow or expertise; disaster recovery often becomes the foremost worry. According to Aberdeen Group, small businesses are twice as likely as larger companies to have implemented cloud-based backup and recovery solutions that save time, avoid large up-front investment and roll up third-party expertise as part of the deal.
✓ Automatic software updates: Here’s why we insist on cloud computing - the servers are remotely located, nowhere to be seen around you which means that they are also out of your jurisdiction for physical maintenance. Once you have paid your suppliers, they take care of everything for you, from software updates to security updates.
✓ Capital-expenditure Free: Cloud computing is not heavy on your pocket unlike other hardware. They have a hassle-free pay-as-you-go solution. You get what you pay for.
✓ Increased collaboration: When you and your colleagues can access, edit and share information/crucial documents at any time of the day from anywhere, doing more and working better becomes easier.
✓ Document control: So, no more sharing and sending emails back and forth with updates and approvals! On cloud, all your files are stored at a central location where everyone who has access to the file sees the updates and the truth in real time. This provides enhanced collaboration which increases productivity.
✓ Security: Because all your data is stored on the cloud, it’s in safe hands. No matter what happens to your system, your data is secure. Any by the way, if you lose your system, fret not. All you have to do is wipe your data.
✓ Environmentally friendly: When you use only the amount of energy you consume, you don’t leave behind a massive carbon footprint.
Alright, now that we have given you a synopsis of cloud computing but you still want to attain further knowledge in cloud computing and its various nuances, here’s something we think will entice you: Manipal ProLearn’s Cloud Computing with AWS.
An overview of Amazon Web Services
In 2006, Amazon Web Services (AWS) began offering IT infrastructure services to businesses on the cloud. Amazon launched Cloud Computing with AWS so that companies could gain from the rich experience of Amazon’s investment in running a large-scale distributed, transactional IT infrastructure. AWS today serves millions customers across the globe providing a highly reliable, scalable, low-cost infrastructure platform in the cloud that powers hundreds of thousands of businesses in 190 countries around the world.
Here’s how organizations use AWS:
- A large enterprise quickly and economically deploys new internal applications, such as HR solutions, payroll applications, inventory management solutions and online training to its distributed workforce.
- An e-commerce website accommodates sudden demand for a “hot” product caused by viral buzz from social media without having to upgrade its infrastructure.
- A pharmaceutical research firm executes large-scale simulations using computing power provided by AWS.
- Media companies serve unlimited video, music and other media to their worldwide customer base.
Organizations pay only for what they use without up-front or long-term commitments.
AWS enables organizations to use the programming models, operating systems, databases and architectures with which they are already familiar. In addition, this flexibility helps organizations mix and match architectures in order to serve their diverse business needs.
Scalable & elastic
Organizations can quickly add and subtract AWS resources to their applications in order to meet customer demand and manage costs.
AWS builds services in accordance with security best practices, provides the appropriate security features in those services, and documents how to use those features.
AWS Host of Solutions
AWS is a comprehensive cloud services platform that offers compute power, storage, content delivery and other functionality that organizations can use to deploy applications and services. AWS self-service means that you can proactively address your internal plans and react to external demands when you choose.
- Application Hosting - Traditionally, businesses have had to build and maintain infrastructure to run on-premises applications. With the Software-as-a-Service (SaaS) model, businesses can consume applications that are hosted online, enabling them to lower their costs by paying only for what they use, enjoy seamless and painless upgrades in functionality, and integrate easily with their existing data and systems. AWS delivers reliable, scalable and cost-effective computing resources on which to host your applications.
- Websites - With Amazon Web Services, you can get your website up and running quickly using applications like WordPress, Drupal and Joomla!
- Backup and Storage – AWS lets you simplify your current backup and recovery environment in the enterprise. It allows you to leverage the on-demand nature of the cloud and automate your backup and recovery processes so they are not only less complex and lightweight but also easy to manage and maintain.
- Enterprise IT Applications – AWS offers a selection of enterprise productivity applications that run as a service. These applications for corporate email & calendaring, document collaboration and virtual desktops make it easy to meet the usability, performance & reliability expectations of employees, while simultaneously delivering on the security and compliance requirements of the most demanding enterprise IT organizations.
- Content Delivery Network – Amazon CloudFront is a content delivery web service. It integrates with other Amazon Web Services products to give developers and businesses an easy way to distribute content to end users with low latency, high data transfer speeds and no minimum usage commitments.
- Databases – AWS provides fully managed relational and NoSQL database services, as well as fully managed in-memory caching as a service and a fully managed petabyte-scale data-warehouse service. You can also operate your own database in the cloud on Amazon.
To sum up...
Taking advantage of Amazon Web Services will allow you to focus on your core competencies and leverage the resources and experience Amazon provides.
