Question

In Cloud architecture, what are the different phases involved? Explain each a. In cloud architecture, what are the building blocks? Explain each

Answer 1

a.There are four phases that basically gets involved in the cloud architecture:

1. Launch phase: it launches the basic services and makes the system ready for communication and for application building.

2. Monitor phase: it monitors the services that is being launched and then manages them so that on demand the user will be able to get what he wants.

3. Shutdown phase: it shutdown the services that are not required first and after all the services gets shutdown, and then it closes the system services.

4. Cleanup phase: it clean up the left out processes and services that is being either broken or didn’t get shutdown correctly.

b.Building blocks in cloud architecture:

1.Development and runtime environment:technologies used in the building and running of applications.

Framework:J2EE, .NET, JSON, AJAX, REST

Web server:Apache, IBM, MS

App server: Tomcat, Weblogic, WebSphere

DBServer:MySQL, SQL, Oracle, DB2

NOSQL DBs: MongoDB, Hadoop

Devel Envir:Eclipse, Visual studio

Cfg deploy:Puppet

2.Operations:technologies used in the deployment and operation of infrastructure and applications.

Service management platform: remedy

Discovery: IBM, BMC ADDM

Monitoring: Splunk, BMC, Tivoli

Hypervisors: KVM, VMWare

HW Mgmt: Cisco, IBM

Storage: object, EMC, IBM

Server/OS:linux, Windows

DevOps is an interesting area of IT focused on the integration of Application Development and Infrastructure Operations

through common process and tooling to achieve continuous and agile deployment of solutions.
