Study Notes
Compute Services in the Cloud
- Compute services encompass various types of virtualized computing resources accessible through cloud platforms
- Different service models cater to diverse needs and requirements
Types of Compute Services
-
Virtual Machine (VM):
- Emulates a physical server on a virtual environment
- Highly customizable, allowing for adjustments to CPU, memory, and storage
- Provides granular control over the virtual machine.
- Multiple preconfigured machine types exist, categorized by compute or memory optimization
-
Micro-service Engine:
- A Platform-as-a-Service (PaaS) offering facilitating efficient deployment and management of microservices
- Facilitates automated scaling, simplifying management in comparison to virtual machines
- Features like auto-scaling and load balancers are inherent parts of the service.
-
Serverless Engine:
- An execution environment where you write code without managing servers directly
- Managed by the cloud provider, optimized for event-driven computing
- Provides a cost-effective solution and simplifies server management tasks
-
Managed Container Clusters (Kubernetes):
- Orchestration system for containers automating container management, including deployment, scaling, and management of containerized applications.
Virtual Machine (Instance)
- All components of a traditional computer virtualized
- Support various operating systems such as Windows and Linux
- Virtual machines run in CSPs' data centers via fiber optic networks worldwide.
- Predefined machine types offering different compute powers, from micro to super (0.2 vCPUs to 96vCPUs)
- Instance types, such as c5n.xlarge, come with various configuration options.
- CPU and memory are available for selection based on requirements.
Provisioning an Instance
- vCPU and memory selection process
- Customization options available from the creation process
- Cost adjustment based on creation or adjustment
- Basic memory rules ensure appropriate range between 0.9GB/vCPU to 6.5GB/vCPU and multiples of 256MB.
Instance Types
- Different instance types, categorized by various optimizations (general purpose, compute, memory, accelerated compute, or storage).
- Different specifications for instances categorized by providers such as Intel or AMD
- Varying storage capacity and I/O operations for different instances
VM Instance Use Cases
- Useful for users requiring full control over VMs
- Compatible with container technologies like Docker
- Allows adding and removing storage, accommodating fluctuating storage demands
- Ideal for applications with specific requirements and persistent state, such as databases
Elastic Compute Engine (EC2)
- An example of a compute engine (a type of compute service)
Micro-service Engine (AWS Beanstalk, GCP AppEngine)
- PaaS service specialized for managing and deploying microservices
- Provides a managed environment for streamlining developer tasks
Serverless Engine (AWS Lambda, GCP Cloud Functions)
- Enables code execution without server management
- Event-driven execution mechanism, making it cost-effective.
Managed Container Clusters (Kubernetes)
- Orchestrates containerized applications, automating container management
- Automates scaling and deployment, offering a robust containerization solution
Components of Kubernetes
- Provides components for control plane, kubelet, kubectl, Kubernetes, and kube-proxy
Important Terms for Kubernetes
- Pods: The fundamental building blocks
- Services: Abstraction layer for network communications
- Deployments: Mechanisms for managing and scaling applications
- ReplicaSets: Control the desired number of Pods running
- StatefulSets: Manage Pods requiring persistent state
- Persistent Volumes: Store persistent data
- Ingress: Handles external access for services
Work chart of Kubernetes
- Describes the interactions and communication between clients, other services, and control plane, including deployments, kubelet, and nodes
Deploy Containerized Web APP
- Steps for deploying a web application utilizing containerization techniques.
- Visual steps using images for deployment process, from packaging to deployment
Summary and Case study of Compute Services in Cloud
- Summarizes different computing as-a-service models
- Case study of a web application providing micro-service-based APIs and static content from Dress4Win
