Study Notes
Scalability and Reliability
- Running components of an application on multiple physical servers provides scalability and reliability by distributing the load and ensuring that if one server fails, others can take over.
Infrastructure-as-Code
- One technology mentioned as a tool for Infrastructure-as-Code is not specified in the text, but commonly used tools include Terraform, AWS CloudFormation, and Azure Resource Manager.
Cloud Computing Eras
- The 'Iron Age' in cloud computing refers to the early days of virtualization, characterized by manual provisioning and limited scalability.
Single Server Drawbacks
- A common drawback of running components of an application on one physical server is that if the server fails, the entire application goes down.
Virtualization and Migration
- Virtualization technology, such as VMware and KVM, allows for the live migration of virtual machines and snapshots for load balancing and fault tolerance.
Cloud Age Challenges
- A major problem in the 'Cloud Age' is the accumulation of technical debt due to rapid development and deployment of cloud infrastructure.
Containerization
- Docker provides containment using Linux kernel features such as chroot, cgroups, and namespaces.
Cloud Operating Systems
- The primary function of Cloud Operating Systems is to manage and orchestrate resources in a cloud environment.
System Virtualization
- System virtualization, such as VMware and KVM, provides a unique feature of full virtualization, allowing multiple operating systems to run on a single physical server.
Containers and Virtual Machines
- Containers and Virtual Machines have in common that they provide isolation and resource allocation for applications.
Infrastructure-as-Code
- The purpose of Infrastructure-as-Code is to manage and provision infrastructure resources through code, ensuring consistency and reproducibility.
Hypervisor Function
- The primary function of a Hypervisor in Cloud Computing is to allocate hardware resources to virtual machines.
Infrastructure-as-Code Problem
- Infrastructure-as-Code aims to solve the problem of manual provisioning and configuration of infrastructure resources, leading to errors and inconsistencies.
Containers vs. Virtual Machines
- Containers and Virtual Machines differ in resource configuration, as containers share the host operating system and resources, whereas virtual machines have their own operating system and dedicated resources.
