What is Cloud?
• Cloud computing means storing and accessing data and programs over the Internet instead of local computer's hard drive or network
![Page 4: Cloud computing](https://reader035.vdocuments.net/reader035/viewer/2022070302/54705202af7959f4398b4649/html5/thumbnails/4.jpg)
Need of Cloud• Reduce Cost– Capex and OpEx is significantly minimized
• Reduce human resources– Frees valuable resources and focus them on delivery
rather than maintaining hardware and software
• Reduce carbon foot print– $12.3 billion in energy savings and 85.7 million
metric tons of CO2 savings annually by 2020

Pros and Cons of Cloud
• Pros– Cost saving – Scalability– Hassle free infra maintenance
• Cons– High Latency– Depended on internet– Data Security

Software as a Service (SaaS)• As a software licensing and delivery model in which software
is licensed on a subscription basis and is centrally hosted
• Example

Infrastructure as a Service (IaaS)• Infrastructure as a Service (IaaS) provides access to computing
resource in a virtualized environment.• Example
Amazon Cloud services
Rackspace

Cloud Setup
![Page 10: Cloud computing](https://reader035.vdocuments.net/reader035/viewer/2022070302/54705202af7959f4398b4649/html5/thumbnails/10.jpg)
Cloud Formation
• Private – Company will take up the ownership and other factors, it will be managed within company’s firewall– On premises - infra at own campus– Externally hosted – hosted for one company but handled by
specialists
• Public – Available to general public or large group. Owned and maintained by cloud servicing companies.
• Hybrid – Mixed of both private and public cloud, management responsibilities are divided between public cloud and private cloud.

Security and Compliance
• Cloud security control is classified under following categories– Deterrent controls - To prevent any purposeful attack on
a cloud system. These controls do not reduce the actual vulnerability of a system.
– Preventative controls – It will safeguard vulnerabilities of the system. cover the attack and reduce the damage and violation to the system's security.
![Page 12: Cloud computing](https://reader035.vdocuments.net/reader035/viewer/2022070302/54705202af7959f4398b4649/html5/thumbnails/12.jpg)
Security and Compliance
– Corrective controls - reduce the effect of an attack. It take action as an attack is occurring.
– Detective controls – It is used to detect any attacks that may be occurring to the system.

Security and Compliance
• There are few cloud providers certified with PCIDSS, HIPAA compliance
• Following are the key requirements to meet any compliance– Business continuity and data recovery – Disaster recovery and
data loss should be recoverable
– Logs and audit trails - properly secured, maintained for as long as the customer requires, and are accessible to them
– Unique compliance requirements - The data centers maintained by cloud providers may also be subject to compliance requirements

Cost Factor• Cost in cloud computing relies on the following characteristics
– A pay-as-you-go model with minimal or no upfront costs
– Usage-based pricing, so that customer costs are based on actual usage
– Scalability, so that customers can dynamically consume more or less resources as and when they required it.

Cost Factor
• 42% - Money spent on hardware, software, UPS, network and Disaster Recovery arrangements.
• 58% - of cost is involved in heating, air conditioning, property taxes and labor costs.
• Owning a data center is much complicated - Recurring expenses and aging of applications and infrastructure may not meet the business expectation

Cost Factor
• A sample data study on an education institution for a student management software.

How to choose right option
• Following points need to be considered before opting any cloud system
– Know the nature of the applications and the workloads at the core of data centers.
– Tethering infra structure for few people is really a huge cost consuming fact. Analyze the number of users for important applications.
– Back ward compatible systems.
