Course Outline
Virtualization Fundamentals
- Operating System Concepts Overview: CPU, Memory, Network, Storage
-
Hypervisors
- The supervisor of supervisors
- "Host" machine and "guest" OS
- Type-1 Hypervisor and Type-2 Hypervisor
- Citrix XEN, VMware ESX/ESXi, MS Hyper-V, IBM LPAR.
-
Network Virtualization
- Brief introduction to the 7-Layer OSI Model
- Focus on the Network layer
- TCP/IP Model or Internet Protocol
-
Focus on a single vertical
- Application Layer: SSL
- Network Layer: TCP
- Internet Layer: IPv4/IPv6
- Link Layer: Ethernet
-
Packet structure
- Addressing: IP Address and Domain Names
- Firewall, Load Balancer, Router, Adapter
- Virtualized Network
- Higher-order abstractions: Subnets, Zones.
-
Hands-on Exercise:
- Familiarize with ESXi cluster and vSphere client.
- Create/update networks in ESXi Cluster, deploy guests from VMDK packages, and enable inter-connectivity between guests in an ESXi cluster.
- Make modifications to a running VM instance and capture a snapshot.
- Update firewall rules in ESXi using the vSphere client.
2. Cloud Computing: A Paradigm Shift
- A fast, inexpensive runway to make products/solutions available to the world
-
Resource sharing
- Virtualization of a virtualized environment
-
Key benefits:
-
Resource elasticity on-demand
- Ideate -> Code -> Deploy without requiring infrastructure
- Rapid CI/CD pipelines
- Environment isolation and vertical autonomy
- Security through layering
- Expense optimization
-
Resource elasticity on-demand
- On-premise Cloud and Cloud Providers
- Cloud as an effective conceptual abstraction for distributed computing
3. Introduction to Cloud Solution Layers:
-
IaaS (Infrastructure as a Service)
- AWS, Azure, Google
-
Choose one Provider to continue later. AWS is recommended.
- Introduction to AWS VPC, AWS EC2 etc.
-
PaaS (Platform as a Service)
- AWS, Azure, Google, CloudFoundry, Heroku
- Introduction to AWS DynamoDB, AWS Kinesis etc.
-
SaaS (Software as a Service)
- Very brief overview
- Microsoft Office, Confluence, SalesForce, Slack
- SaaS builds on PaaS that builds on IaaS that builds on Virtualization
4. IaaS Cloud Hands-on Project
- The project uses AWS as the IaaS Cloud Provider
-
Use CentOS/RHEL as the operating system for the rest of the exercise
- Alternatively, Ubuntu will also work, but RHEL/CentOS are preferred
- Obtain individual AWS IAM accounts from your cloud admin
-
Each student must perform these steps independently
- The ability to carve out your own entire infrastructure on-demand is the best demonstration of the power of cloud computing
- Use AWS Wizards -- AWS online consoles -- to accomplish these tasks unless otherwise mentioned
-
Create a public VPC in us-east-1 Region
-
Two Subnets (Subnet-1 and Subnet-2) in two different Availability Zones
- See https://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_Scenarios.html for reference.
-
Create three separate Security Groups
-
SG-Internet
- Allows incoming traffic from the Internet on https 443 and http 80
- No other incoming connections allowed
-
SG-Service
- Allows incoming traffic only from security group SG-Internet on https 443 and http 80
- Allows ICMP only from SG-Internet
- No other incoming connections allowed
-
SG-SSH:
- Allows SSH:22 incoming connection only from a single IP that matches with the public IP of the student’s lab machine. In case the lab machine is behind a proxy, use the public IP of the proxy.
-
SG-Internet
-
Two Subnets (Subnet-1 and Subnet-2) in two different Availability Zones
- Deploy an instance of an AMI pertaining to your chosen OS -- preferably the latest RHEL/CentOS versions available in AMIs -- and host the instance on Subnet-1. Attach the instance to SG-Service and SG-SSH groups.
- Access the instance using SSH from your lab machine.
- Install the NGINX server on this instance
- Place static contents of your choice -- html pages, images -- to be served by NGINX (on port 80 over HTTP) and define URLs for them.
- Test the URL from that machine itself.
- Create an AMI image from this running instance.
- Deploy that new AMI and host the instance on Subnet-2. Attach the instance to SG-Service and SG-SSH groups.
- Run the NGINX server and validate that the access URL for the static content as created in step (i) works.
-
Create a new "classic" Elastic Load Balancer and attach it to SG-Internet.
- Note the difference from Application Load Balancer and Network Load Balancer.
- Create a routing rule forwarding all http 80 and https 443 traffic to an instance group comprising the two instances created above.
- Using any certificate management tool -- such as java keytool -- create a key-pair and self-signed certificate and import the certificate to AWS Certificate Manager (ACM)
5. Cloud Monitoring: Introduction and Hands-on Project
- AWS CloudWatch metrics
-
Go to the AWS CloudWatch dashboard for the instances
-
Retrieve the relevant metrics and explain the variability with time
- https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/viewing_metrics_with_cloudwatch.html
-
Retrieve the relevant metrics and explain the variability with time
-
Go to the AWS CloudWatch dashboard for the ELB
- Observe the ELB metrics and explain their variability with time
- https://docs.aws.amazon.com/elasticloadbalancing/latest/classic/elb-cloudwatch-metrics.html
6. Advanced Concepts for Further Learning
- Hybrid Cloud -- on-premise and public cloud
-
Migration: On-premise to public cloud
- Application code migration
- Database migration
-
DevOps
- Infrastructure as a code
- AWS CloudFormation Template
-
Auto-scaling
- AWS CloudWatch metrics to determine health
