Choice of technology and deployment environment

Choice of technology and deployment environment 

Practical scenario

    As a part of our Assignment  our solution for the travel agency is Whole Solution will be implemented in Amazon Cloud but, it will be a hybrid cause in the solution it is to move the part by part from the existing network it not going to be a big ban. Customer already got the in-house server farm and in this solution those components will be moved one part or bunch of part at a time to the AWS cloud. Until the whole system is moved to cloud this is going to be a Hybrid solution.

How it going to benefit the company businesses and for the future

    Cloud is the main trend in the new Technology world. Most of the companies is moving with the cloud solutions because it will help lot for the companies and easy to mange. Moving cloud to mean less work for IT team and the Company don't want to worry about maintain IT equipment ans their security. because all of these are managed by the Cloud service provider (In this case Amazon AWS). It going to save the cost that required for all the IT equipment  software ,security (software and physical). It team have to maintain company system and backups only. Although all the backup hgas benn automated it's one of the best practises that to test backup time to time the it will give an good idea about Recovery Time Objective RTO  and  Recovery Point Objective RPO.

 

Why AWS ?   

Amazon is one of the top cloud services in the cloud [Figure 1]. that's why we suggest go with the AWS and the main thing is "YOU PAY AS YOU USE" company have to pay only if they use the services only.

The main process of moving the existing environment to the AWS cloud will be done in 7 phases.

1^st phase would be setting up the main environment in the cloud such as Configure the servers ADDC

2^nd phase moving the tape backup

3^rd phase would be moving the back-end of the system

4^th phase would be moving the customer accounts 50 – 60 bulk at a time

5^th Phase moving front end of the web site

6^th Phase checking the whole system in the cloud environment.

7^th Close the local server farm.

The AWS services that we are going to use for this process is as below.

Region – The Main region will be Asia Pacific (Sydney) ap-southeast-2 and For Backup the Other region would be US East (N. Virginia) us-east-1.

AWS IAM – For the Administrators and developers will log using IAM


AWS VPC- VPC with four subnets between two AZ’s (A and B) and each AZ will have Public Subnet and Private Subnet. Same Configuration will be in Other Regions as well.

Availability Zone  There will be Two Availability Zone one will be in us-east 1a and other will be in us-east1b.

NAT Gateway – This will help to access the RDS and EC2’s in the Private subnet.

AWS Internet Gateway – Internet gate way will be attaching to the VPC for Internet Traffic.

EC2’s – AWS EC2 instances with AMI Linux will be use for the Web server and for the management console.

Route53 – For the Domain (DNS) with existing Domain services will be connect to this.

AWS Storage Gateway- Backup the data from on premises.

S3 Bucket - For the storage for files and enable Cross region with versioning for backup.

S3 Glacier Deep Archive – Backup data with archiving.

Cloud Endure Disaster Recovery- To Deployed the same infrastructure in Other regions.

Cloud Front – The Cloud front will be used as Content delivery network (CDN).

Cloud watch – Cloud watch will be used to monitor and to get the logs.

Guard Duty – Guard Duty will use as the virus guard.

Cloud Trail – Audit the API calls.

Lambda – To run codes code without provisioning.

Web Development – For the Web server use httpd and php for web development.
 
Amazon RDS – Amazon Data base services using MySQL for the data base with back end access.

Auto scale - Auto Scale because it will help to share the resources. This for the High scalability.

Load balancer – Using the load balancer the site will be able to balance the load between the two Availability Zone and for the High availability.

After moving the whole system to the Cloud as a part of the plan IT team member's will be provide with the training about cloud. Other staff will be have trainings regarding the new system. After moving the whole system the Data center will be fully close.
