Amazon Web Services provide you a low cost and highly scalable infrastructure platform in the Cloud. It has been adopted by thousands of businesses globally. It helps you understand AWS and how its benefits can be utilized for improvement and growth.

Do you know Amazon has its own cloud Services.

Commonly known as cloud computing, these are the web services in the form of IT infrastructure that became  offered by Amazon in the year 2006. They were well known as Amazon Web Services (AWS). Businesses no longer have to plan for IT infrastructure such as servers in advance. They can access thousands of servers virtually within minutes by leveraging the power of cloud computing. AWS eliminates up-front capital infrastructure costs that help scale up a business. It is a smooth sailing product market that fits hundreds of thousands of businesses. It gives the end user the flexibility to scale up and down according to the business needs.

There are few factors that make AWS a top notch cloud service provider among its customers. We can discuss a few of them :

Why use Amazon Web Services?

Some key factors that make Amazon AWS a world leader in the cloud market.

Enhanced Security
Amazon Web Services provide a durable and secure technology platform. To ensure the safety and integrity of your data Amazon’s data centers and services have several layers of physical and operational security to implement best practices in security along with offering documentation on how to make use of the security AWS features. It ensures the availability, integrity, and confidentiality of your data and provides end-to-end privacy and security.

Cost-Effectiveness
One of the prominent Amazon Web Services advantages includes its pay-as-you-go pricing model. This implies that you pay only for the specific service that you subscribe to and only for the time you need it for. You only pay for the services for what you consume and if you wish to stop using then there are no additional costs or termination fees

Flexibility and Openness
Amazon web services are platforms for operating systems and languages. You are able to select the programming model or development platform that can be most beneficial for your business.

Elasticity and Scalability
AWS lets you easily leverage scalability, it can easily manage the workload increase by allocating the resources based on the demand, that too within minutes. This feature is very useful in terms of cost where according to the workload we could either upscale the resource or down-scale on the fly.

The most interesting part is that these can be even automated with the help of some conditions ie, when a threshold value for CPU usage is hit automatically a new instance gets launched.

Reasons why you need EC2 compute
Elastic Compute Cloud (EC2) provides you the facility to use Amazon’s environment for computing and control your computing resources completely. It helps rapidly scale capacity based on your computing needs as Amazon EC2 allows you to get and boot new server instances in a few minutes.It also protects against common scenarios of failure and provides developers with tools to develop mobile applications that are failure resilient. Amazon EC2 eliminates your need to invest in hardware upfront and can develop and deploy applications faster

Features of Amazon Web Services EC2?

AWS EC2 has many key features that help develop enterprise-class and scalable apps, which are resilient to failure. Some of them are listed below.

 Amazon Elastic Block Store (EBS)
EBS provides constant storage for instances of Amazon EC2. Amazon EBS volumes are attached to the network and persist without being dependent on an instance’s life. These can be attached as a standard block device to a running Amazon EC2 instance or used as the boot partition of an Amazon EC2 instance and are highly reliable.

EBS-Optimized Instances
EBS-optimized instances make it possible for EC2 instances to utilize the IOPS provisioned on an EBS volume completely. Depending on the type used, throughput anywhere between 425 Mbps and 14,000 Mbps can be delivered by EBS-optimized instances between Amazon EC2 and Amazon EBS.

Elastic IP Addresses
Static IP addresses that can be used for dynamic cloud computing are known as elastic IP addresses. An elastic IP address is not associated with a particular instance but with your account and, until you release it, you can control that address.By remapping your public IP addresses programmatically to any instance in your account, elastic IP addresses let you mask availability zone failures or instances.

Amazon Virtual Private Cloud

It defines a virtual network where you can launch AWS cloud resources. This can be done through a section of the AWS cloud logically isolated with the help of Amazon VPC. You can configure network gateways and route tables, create subnets and choose your own IP address range. Because you can control your own virtual networking environment completely through Amazon VPC.

You can also create a hardware virtual private network (VPN) connection between your VPC and your corporate data center to use AWS cloud as an extension of your corporate data center.

Amazon CloudWatch
Amazon CloudWatch helps to monitor Amazon cloud applications and resources. Network traffic, disk reads and writes, and CPU utilization are the key metrics that Amazon CloudWatch provides you for visibility into overall demand patterns, operational performance, and resource utilization.

You can set alarms, view graphs, and get statistics for your metric data.

Auto Scaling

In accordance with the conditions you outline, auto-scaling lets you scale your Amazon EC2 capacity up or down. You can minimize the costs of spikes or lulls in demand through auto-scaling that automatically scales up or scales down the Amazon EC2 instances you are using.

Elastic Load Balancing

This automatically allocates incoming application traffic to various Amazon EC2 instances. Responding to incoming app traffic, elastic load balancing provides the load balancing capacity required to help you get greater tolerance for faults in your apps.Elastic load balancing sends traffic to healthy instances until the unhealthy instances have been repaired. For the consistent performance of mobile apps, elastic load balancing can be enabled within one or more availability zones.

There are three types of Elastic Load Balancers available. You can use the one best suited for your work.

  1. Classic Load Balancer
  2. Application Load Balancer
  3. Network Load Balancer

Classic Load Balancers
Classic Load Balancer provides basic load balancing across multiple Amazon EC2 instances and operates at both the request level and connection level. Classic Load Balancer is intended for applications that were built within the EC2-Classic network.

They are less intelligent than the Application Load balancers.

Application Load Balancers
Application Load Balancer facilitates load balancing of HTTP and HTTPS traffic by providing advanced request routing targeted at the delivery of modern application architectures, with a focus on microservices and containers. The Application Load Balancer operates at the individual request level and directs traffic to target within Amazon Virtual Private Cloud based on the content of the request.

Network Load Balancers
The load balancer allocates incoming traffic across multiple targets, such as Amazon EC2 instances which increases the availability of your application. By adding one or more listeners to your load balancer.

Enhanced Networking
This EC2 feature improves the packet per second performance, along with providing lower network jitter and lower latencies. With the enhanced networking utilizes a new network virtualization stack that holds power to offer better I/O performance and low CPU utilization. All you need to do is launch the HVM AMI in VPC, and install a compatible driver.

VM Import/Export
This EC2 feature helps the import of virtual machine images from the source to EC2 instances and export to the same source at any given time. You get to consign any previously imported EC2 instances to its source whenever the need be. There is a standardised amount of usage threshold beyond which there are additional charges to use the service.

What you learn from here is that

In the current market space where on-demand services are on the rise, Amazon Web Services has emerged as a viable solution for businesses looking for reliable, scalable, and inexpensive cloud computing services with distinct operations in 22 geographical regions, AWS helps companies to manage a range of services including development, game development, data processing, warehousing etc. Main advantage of AWS is that your business gets access to EC2 which in turn provides a virtual cluster of computers through the internet. Whether you are a startup or an established enterprise, AWS is an ideal solution that can offer extensive cost savings, maximum uptime, and continuous support a great ROI
