- 3. Introduction Cloud computing as a style of computing in which scalable and elastic IT-enabled capabilities are delivered as a service using Internet technologies. -Gartner 3 Scalability means managing increase/shrinkage in demand over time. Elasticity means on-demand service. Consume what you need and when you need. If you are observing a spike in traffic/demand of your product, increase the computing power and storage at that particular time. If you are observing a decrease in demand, down size the resources at that specific time. 1% 7% 13% 44% 35% Relevance of Cloud Computing It is important but not critical Don’t know No direct Contribution Makes Contribution, but not understood It is critical to business strategy and success Online survey, TNS Infratest
- 4. Types of Cloud Service Model Cloud Computing Service Model Software as a Service Platform as a Service Infrastructure as a Service • Providing computing infrastructure such as virtual server space, bandwidth, network connections, IP addresses, and load balancers • It is about hosting. • Example: Amazon Web Services (AWS), Cisco Metapod, Microsoft Azure, Google Compute Engine (GCE) • It is similar to middleware • Automatically and transparently configures servers in the background • Typically includes operating system, programming language execution environment, database, web server. • Example: AWS Elastic Beanstalk, Windows Azure, Heroku, Force.com • Deliver software over the Internet • Instead of installing and maintaining applications, users access them via the Web • Applications feature a multi- tenant architecture with the same infrastructure and code base • Example: Google docs, Gmail, Microsoft office365 4
- 5. Cloud Readiness Test 5 While cloud computing is revolutionary, it may not be the perfect solution for all situations. Below questionnaires will help in deciding Q1. Does your start up need custom hardware/software? If answer is Yes, find out specific hardware configuration is been provided by any cloud provider or not. Custom software normally can’t be installed. Q2. Does your start up work with large amount of data? Data transfer is a variable cost and it may lead to very high cost. So a cost benefit analysis is required before moving to cloud. Q3. Are you planning to undergo any compliance/certification for product? Normally, before entering a particular sector or region, organization undergo compliance certification (e.g. HIPPA & PCI DSS, FERPA, and US EU Safe Harbor). If you are planning for undergoing any such compliance then proper due diligence is required. Q4. Does the cost of cloud computing exceeds building in-house/outsourcing/virtualized/Co-location? Proper Cost benefit analysis, hidden cost analysis and opportunity cost analysis required These questions should cause careful thought prior to adopting or avoiding the cloud.
- 6. Total Cost of Ownership (TCO) 6 It is the process of evaluating cloud against other models of computing such as on premises, virtualized and Co-location TCO Evaluation Methodology • Acquisition cost • Operating cost • Decommissioning and retiring system • Comparing direct and indirect cost • Opportunity cost (Time you can spent on your business if cloud provider takes care of infrastructure) Acquisition and Operating Cost includes • Server cost (hardware + software) • Storage cost (hardware + system admin) • Network cost (hardware + n/w admin) • IT labor cost
- 7. Why move to Cloud 7 Organizations across sectors get hold up in the upfront price of software and fail to aware about the total cost of ownership (additional hardware, support, etc.). Healthcare companies often invest nearly above 70-75% of their IT budgets on maintaining internal infrastructure. Cloud services enables you to pay for the resources usage. It will help to take advantage of scale and reliability, two things that most startups can’t afford internally. Cloud enables other digital technologies such as social media, mobility, big data and advanced analytics. Reactively scale up and down cloud based resources that have random or cyclical demand increase, paying only for what you use and when you use; simplify geographical expansion and load distribution; It also helps to avoid building expensive physical private webserver and application servers 10 Reasons Total cost of ownership Mobility High Availability Ease of Management Disaster Readiness No Server Maintenance Scalable Computing Enabler of your business goals Fast to Market Security
- 8. Cloud Deployment Model - Benefits & Risk 8 Cloud Deployment Model Private Cloud Public Cloud Hybrid Cloud • Cloud infrastructure is provisioned for exclusive use and it may exist on or off premises • Good option for organization that already own datacenter and developed IT infrastructure and have particular needs around security or performance • Risk: Migration of data and application • Cloud infrastructure is provisioned for open use and exist on the premises of the cloud provider • Risk: Data and processing environment are not under control of enterprises, which for applications or data with a security requirement may raise concerns • Cloud infrastructure is a composition of two or more distinct cloud infrastructures • It combines benefits of the controlled environment in private clouds and rapid elasticity of public clouds • Risk: seamless integration between the Private and the Public cloud
- 9. How to move to Cloud 9 Leadership Team Initially leadership/management team should take decision how the product/application will be deployed at client’s end. E.g. will it be deployed on premise or on cloud or on both. Code preparation Once management team has decided that the application will be deployed on cloud or both on cloud or on premises the application development needed to betaken care. Application is cloud ready if it can be seamlessly deployed on cloud. For example while developing application we need to take care about file system, avoid OS specific features, keeping remote store for temporary information. Infrastructure Architecture Once the application is cloud ready we need to decide we need to go for public/private/hybrid cloud. Then what should be the architecture, should there be public subnet/both public private subnet. How different components (e.g. web server, app server, database, load balancer) will interact with each other. What should be the type and sizes of the instance/component. Security Security is a very vital aspect. We need to take measures so that we can make sure somebody outsider can’t access the data/application. For example authorizing a particular IP for accessing, password need to be hashed/salted. Testing Preparing a test environment mirroring to the production and testing the application end to end before go live.
- 10. Cloud Infrastructure Architecture 10 VPC with single public subnet Recommend if you need to run a single-tier, public-facing web application, such as a blog or a simple website VPC with public and private subnet Recommend if you want to run a public- facing web application, while maintaining back-end servers that aren't publicly accessible. Example is a multi- tier website, with the web servers in a public subnet and the database servers in a private subnet VPC with public and private subnet and hardware VPN access Recommend if you want to extend your network into the cloud and also directly access the Internet from your VPC.
- 11. Use Cases 11 Use Case 1: Worried about hosting applications/website? Host your Website/application on Cloud with less cost and minimal effort Use Case 2: Need Proof of concept before building complex infra? For applications which require complex infrastructure for testing environment, there cloud can be used as an eliminator. It is a cost effective alternative for proof-of concept services try out without capital investment User Case 3: Facing shortage of infrastructure? For load or performance testing, instead of real machines, cost effective cloud solutions can be used User Case 4: Looking for protecting your business? As part of disaster recovery plan, cloud infrastructure/environment can be stand as a hot standby (live replica of files and data)
