Why Cloud Computing?
Due to the fact that data can be replicated at numerous redundant sites on the network of the cloud provider, cloud computing makes data backup, disaster recovery, and business continuity simpler and less expensive.
Why Azure?
Azure makes it simple to move between on-premises and public clouds and provides a stable, consistent platform. To enhance usability and speed, Azure offers a wider selection of hybrid connections, such as virtual private networks (VPNs), caches, content delivery networks (CDNs), and ExpressRoute connections.
Benefits
- Cost Effective – Pay as you go
- Secure – Cloud services can by secure by default
- Reliable – Backups, Recoveries, Fault tolerance, Replication and more
- Scalable – Vertical and Horizontal
- Elastic – Automate
Deployment Models
- Public Cloud – Everything built on cloud provider
- Private Cloud – On premises
- Hybrid – On premise & Cloud service provider
- Cross Cloud – Multi cloud provider
Total Cost of Ownership
CAPEX v/s OPEX
An organization’s Capital Expenditures (CapEx) are investments made for long-term gains in the future. CapEx includes purchasing computers, servers, and other hardware required for on-site data centers.
On-Premise
– Software License Fee
Which means we have to pay alot of money and have to maintain it by ourselves.
– Implement
– Configuration
– Physical Server
– Hardware
– IT Personal
– Maintenance
The ongoing expenses incurred by daily activities are known as Operational Expenditures (OpEx). The upfront infrastructure investment is made by the cloud provider, and you only pay for the resources you utilize when you do so, making a subscription price for cloud services deemed OpEx.
The Provider
– Subscription Fee
Customers only have to do:
– Implement
– Configuration
Architect Terminology
- Availability
- Scalability
- Elasticity
- Fault Tolerance
- Disaster Recovery
- High Durable
Azure Load Balancer – To distribute traffics to multiple server.
Evolution of Computing
Regions and Geography
- Region – Grouping multiple datacenter (Availability Zone).
- Geography – Discrete market, data residency & Compliance boundaries.
- Paired Region – Only on region is updated at a time to ensure no outages.
- EX: Azure Geography – Redundant Storage.
EXPLORE REGION
- EX: Azure Geography – Redundant Storage.
Service Availability
Not all azure cloud services are available in every region
You can check the Azure services you need are available in the datacenter region that you’re considering.
- Recommend Region – Designed to support availability zones.
- Alternate Region- Help to optimize latency and provide a second region for disaster recovery needs.
- General Availability
Azure Cloud Service
- Foundational
- Mainstream
- Specialized
Special Region
Specialized regions to meet compliance or legal reasons.
Availability Zones
An availability zone is physical location made up of one or more datacenters.
- Region generally contain 3 availability zones
- Datacenter within a region ill be isolated from each other
Azure is an combination of a fault domain and update domain
- Fault domain – Avoid single point of failure
- Update domain – Updating hardware & software all together
- Availability set – Logical grouping
