ITC561 Cloud Computing: DTGOV Webserver Migration to AWS IaaS Plan

This project presents a comprehensive analysis of DTGOV's plan to migrate its webservers to an IaaS instance within the AWS cloud environment. The project delves into the current infrastructure, outlining the existing data centers and their operational characteristics, including the significant volume of data handled. It explores the benefits of migrating to AWS, such as increased service availability, reduced operational costs, and enhanced development velocity. The project then outlines the essential cloud architecture, focusing on IaaS and PaaS services, and recommends a hybrid cloud model for scalability and accessibility. It further details the impact of AWS on DTGOV, including improved service availability, efficient handling of heavy loads, and enhanced security. The project also covers cloud architectures in AWS, including discovery services, CloudWatch, Server Migration Service, Config, and Database Migration Service. The project concludes with a detailed migration plan for DTGOV, encompassing evaluation, planning, application design, and execution. The project also includes an introduction to Office365 and SharePoint and their benefits to DTGOV.

Topic One

Webservers of DTGOV
– DTGOV operates on three datacentres
– One for low-level platform servers
– The other two both for low level and
mainframes
– Datacentres host more that 100,000
servers
– More that 10,000 TB of data is handled.

Introduction to AWS
– AWS is one of the top most cloud providers in the organization right now
– The selection of AWS is done for the DTGOV organization for their trial of initial
webserver.
– The webserver would be able to address all the drawbacks that are currently
present in the organization.
– AWS provides the organization with a large variety of services such as IaaS, PaaS
and SaaS

Benefits of migration to AWS
– Increase the service availability
– Reduces the operations costs
– Increased development velocity
– Provides a wide ranges of services
– Lowers the time for market
– Reduces the response time

Essentials of the cloud
architecture
– DTGOV requires to implement the IaaS and PaaS services for their migrating
process.
– It is advisable that the DTGOV organization exploits the hybrid model for cloud
architectures for their migration process
– The scalability and the accessibility would be very easy for the authorized users
in the system

Benefits of IaaS for DTGOV
– The resource can be distributed as a
service
– Very helpful during expansion
– Provides efficient scalability
– Allows multiple users on a single
hardware
– Pay per use facility available

Effect of AWS on DTGOV
– AWS would help DTGOV services to be available to users at all times
– The heavy loads would be handled efficiently by AWS
– The users of DTGOV would be able to able obtain download capabilities
according to their requirements
– The AWS services would secure the DTGOV servers to a great extent
– The usage reports for the DTGOV organization would be provided by the AWS
services

Cloud architectures in AWS
– AWS Discovery Services
– Amazon CloundWatch
– AWS Server Migration Service
– AWS Config
– AWS Database Migration Service

AWS Discovery Service
– The cloud migration planning is
process is simplified
– The application dependencies are
identified
– The application performances are
measured
– The multi-tier applications are
discovered.

Amazon Cloud Watch
– The Amazon Cloud watch is basically
a Application monitor
– It also monitors the infrastructure
– Provides system-wide visibility to
the DTGOV organization
– Provides the users the options to
create alarms and sends
notifications
