Platform and Oracle Cloud
Version: 1

2. Why Cloud Computing ?
Cloud technologies are becoming one of the major investments for all sizes of organizations,
instead of buying, owning, and maintaining physical data centers and servers, you can access
technology services, such as computing power, storage, and databases, on a needed basis
from a cloud provider like (AWS, Azure, Oracle and Oracle ). The goal generally includes
plans to reduce costs, consolidate billing, ensure server availability and plan for
disaster recovery.

3. Who is using cloud computing?
Organizations of every type, size, and industry are using the cloud for a wide variety of use cases, such
as data backup, disaster recovery, email, virtual desktops, software development and testing, big data
analytics and customer-facing web applications. For example, healthcare companies are using the
cloud to develop more personalized treatments for patients. Financial services companies are using
the cloud to power real-time fraud detection and prevention. And video game makers are using the
cloud to deliver online games to millions of players around the world.
Benefits
• Flexibility
• Work from anywhere
• Low-Cost Disaster Recovery
• Environmentally Friendly
• Do more with less

4. Computing Advantage and Disadvantage
What’s good—and what’s bad—about cloud computing? Let’s look
What's good.
• Lower IT Infrastructure Costs
• Fewer Maintenance Issues
• Lower Software Costs
• Data Safety
What's bad.
• Requires a Constant Internet Connection
• Stored Data Might Not Be Secure
• Downtime

5. Types of cloud computing
Services provided by cloud computing can be split into four major categories.
 Infrastructure-as-a-Service (IaaS)
It gives us a big power but requires a lot of configuration. IaaS gives a virtual machine which we have to maintain. The
difference between IaaS and having a physical server room is we don’t have to buy any physical computers and we can
have servers in various parts of the world
 Platform-as-a-Service(PaaS)
PaaS is similar to SaaS except for one major difference. Rather than offering software that is delivered over the web,
PaaS offers a platform for the creation of software delivered over the web. Platform as a Service is a simple way to
deploy an app in a given technology (e.g., Node.js, Ruby, PHP, Python, Java, .NET).
 Software-as-a-Service (SaaS)
SaaS is delivered over the web and is primarily designed for the end user. It is usually offered on a subscription basis or
as a pay-as-you go model. Because of its accessibility, this model is rapidly growing in popularity and market indicators
predict even further growth.
 Data as a Service(DaaS)
Database as a service – it’s a platform which hosts our database providing backups, clustering, and high availability. The
most popular DBaaS are Amazon Aurora, Amazon DynamicDB, mLab, IBM Cloudant and MongoDB Atlas.

8. Which is the best cloud service in the end?
Amazon Web Services(AWS)
• An innovator of online commerce, it stands to reason that Amazon would develop a robust cloud
computing platform for enterprise. The vast global framework and disbursement of Amazon Web Services
is what the entire platform is built upon. The service is divided between regions, availability zones (AZ’s),
and what are called edge locations. Altogether, AWS has 22 regions located around the world, 14 AZ’s,
