Cloud Computing & Application Planning for Cloud

  1. 1. Cloud Computing Migrating your app to cloud Presented By: Azhar Khan
  2. 2. Agenda:  Cloud computing  Cloud Service  Application features required for Cloud environment  Application migration planning
  3. 3. Cloud computing  Network of servers on the Internet for sharing resources.  Elastic resources i.e. we scale up or down the resources as per our demand.
  4. 4. 11/05/16 Cloud service  Software as a Service (SaaS)  Platform as a Service (PaaS)  Infrastructure as a Service (IaaS)
  5. 5. 11/05/16 Cloud service Software as a Service (SaaS)  Software on demand & subscription based licensing.  E.g.: Microsoft Office 365, Google Apps etc. Advantages:  No need to purchase software & their frequent updates.  Eliminates the data center cost.  High scalability. Disadvantages:  Dependency on the service provider.
  6. 6. 11/05/16 Cloud service Platform as a Service (PaaS)  Platform to develop, maintain and run applications without maintaining the infrastructure, middleware frameworks, database etc.  E.g.: Windows Azure, AWS etc. Advantages:  Various benefits in application testing & deployment.  Backup & recovery as a part of service.  Highly scalable and dynamic allocation based on geo-locations. Disadvantages:  Data security  Integrating PaaS with in-house systems.`
  7. 7. 11/05/16 Cloud service Infrastructure as a Service (IaaS)  Infrastructure, dedicated or virtual servers.  E.g.: Windows Azure, Amazon EC2 etc. Advantages:  Various resources like firewalls, load balancer, VM disk image etc.  Highly scalable infrastructure. Disadvantages:  Off-premise data storage.
  8. 8. 11/05/16 Application features required for Cloud  Architecture should not be specific to any topology  Designed to take advantage of parallel architecture of cloud  Design should consider the quantity of data transferred to the various clients (i.e. mobile, web etc.) as client may have limited bandwidth  Data security is a major concern, so proper measures should be taken  Service-Oriented architecture should be adopted
  9. 9. 11/05/16 Application migration planning  Analyzed technically for performance, design, data security etc.  Enterprise should consider the compliance issues, security concerns etc.
