Now that we have understood AWS at a 50000 ft view, still some things are not clear as the first post is all about cloud and what Amazon AWS can do for you. In this post we will see

  • What all I will get with AWS?
  • What are the maintenance costs? etc.
  • Do I need to move my existing datacenter whole to AWS or I can keep some data as is and some in AWS?
  • Will I get everything which is there in my Datacenter as a service in AWS?
  • How easy it is there??

The answers to these questions lies with the understanding of list of services offered by AWS in various fields like compute, network, Content Delivery etc. At the time of this writing there are 1000+ services offered by AWS. Of course not everyone needs to know everything. Hence we are going to take a look at few of the services and a one liner about how they help us.

AWS Compute Services Introduction

These services offered to cater to the computational needs of the user. That is the basic server machines, desktops laptops etc. So we have some of the services with names and icons listed below-

Amazon EC2(Kind of servers)– Just as we have our servers at our datacenters, we have Amazon EC2 in AWS. These are the virtual machines which are provided to us based on the configuration which we choose.

Auto-Scaling(Kind of hardware upgrading)- Automatic scaling up or down feature for EC2 instances. This means the VMs you have taken above can be easily replicated to provide you more when you require them and can be removed when you don’t require them 

Elastic Load Balancing(Kind of clustering) – To distribute the traffic across multiple EC2 instances. It is similar to a physical load balancer that we have in our datacenters. This ensures your EC2 instances are not overloaded.

Amazon Workspaces – Workspaces are nothing but fully managed desktops in Cloud. So when you require a desktop with certain amounts of CPU, memory, storage, and a choice of applications, workspace will help you.

AWS Lambda- Lambda is service which provides you a platform to run your code based on some events. This means on certain trigger (say some update on Database), a code can run on a platform and do desired task.

AWS Networking Services Introduction

These include those services which offer you an option to extend connectivity between your physical datacenter to the one on cloud. Along with this you can set up your own private network with resources in public cloud. Services are-

Amazon Route 53(Kind of DNS service) –This one is the DNS (domain name service) which helps you register your domain and maps it to IP address

AWS Direct Connect(Kind of VPN)-This service helps you establish dedicated network between your enterprise and Cloud resources by passing the internet

AWS Storage Services Introduction

These include those services which offer you an option to extend connectivity between your physical datacenter to the one on cloud. Along with this you can set up your own private network with resources in public cloud. Services are-

Amazon S3: Simple storage Service which is like a distant storage which stores the data as objects which allows to store and retrieve large amount of data in cloud

Amazon Elastic Block StorageBlock storage for EC2 instances which are similar to hard drives attached to our instances. Transactional Databases and local storage are done on EBS and attached to EC2

Amazon GlacierLow-cost storage optimized for data archiving and backup. It is highly secure but very slow and is ideal for storing less utilized data

 AWS Storage GatewayA service that connects an personal datacenter based software appliance with cloud-based storage in a secured manner

AWS Database Services Introduction

These set of services offers you to set up fully managed and scalable databases in cloud

Amazon RDS-Relational Database service which helps you establish a relation DB in cloud using your favorite MYSQL, , Oracle, SQL Server or PostgreSQL and Aurora DB

To summarize, we can say AWS is complete solution to traditional datacenter set ups. Still we need to know more about the billing on usage for AWS services to decide and analyse whether Cloud is better in our case or not. Below are next posts we are planning.

Introduction to how billing works in AWS

Introduction to AWS market

Introduction to AWS Global reach.
