Cloud Computing, High Availability, Scalability,
Elasticity, Agility, Fault Tolerance, and Disaster
Recovery
Principles of economies of scale
Capital Expenditure (CapEx) vs Operational
Expenditure (OpEx) and their differences
, Consumption-based model
IaaS, PaaS, SaaS and their differences
Public, Private, Hybrid cloud and their differences
Scalability is the ability to scale, so allocate and
deallocate resources at any time
Elasticity is the ability to scale dynamically
Agility is the ability to react fast (scale quickly)
Fault tolerance is the ability to maintain system
uptime while physical and service component
failures happen
Disaster Recovery is the process and design
principle which allows a system to recovers from
natural or human induced disasters
High Availability is the agreed level of operational
uptime for the system. It is a simple calculation of
system uptime versus whole lifetime of the system.
Means system is designed to run for very long
period of time.
o availability = uptime/(uptime + downtime)
What is Cloud Computing?
Cloud computing is the delivery of computing services
such as server, storage, database, network. And all of
,them are over the internet that is on cloud and you
typically pay as you go. What you use you pay for that.
Cloud Deployment Models:
1. Public Cloud
Owned by cloud service provider.
There is no local hardware to manage.
Cloud users can save additional cost by sharing
computing resources.
Azure is an example of public cloud.
No Capex: Need to pay only what you use.
Agility
Consumption-based: pay as u go
No maintenance
High Availability and scalability
High reliability
2. Private Cloud
Owned and operated by organization. Create cloud
env in their own data center.
When they have data that can not be exposed
publicaly.
Improved security
More flexibility
High Scalability
, 3. Hybrid Cloud
Combination of both public and private cloud.
Creating website on public cloud and linking
secured database which is on private cloud.
Layer Cloud Provider Own Datacenter
Public ✅ ✖
Hybrid ✅ ✅
Private ✖ ✅
Cloud Service Models:
Iaas:
Build pay as u go by renting infrastructure by renting
servers, virtual machines, storage, networks, and
operating systems from a cloud provider.
Paas:
Provides env for building testing and deploying software
applications, without focusing on managing underlying
infrastructure.
