Study Notes
- Containers are units of software that include application code, libraries, and dependencies, packaged to run consistently across different environments.
- Containers use operating system (OS) characteristics like namespaces and cgroups to isolate programs and control resources.
- Containers share the OS kernel with the host machine and do not require a separate OS instance, making them compact and resource-friendly.
- Containers can boot up quickly, support modern development patterns, and enable microservice architectures for more granular scaling.
- Cloud computing refers to services provided via the internet, including infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS).
- Cloud computing can be public or private and offers quick, scalable access to resources through a remote data center or cloud infrastructure.
- IaaS providers, like Amazon Web Services, offer virtual server instances, storage, and APIs for users to transfer workloads to a VM.
- PaaS providers offer development tools on their infrastructures, allowing users to access technologies and build and host applications over the internet.
- SaaS applications are software services accessed through the internet, providing access to application software and databases.
- Cloud computing deployment models include private cloud, public cloud, and hybrid cloud, with varying levels of access and control.
- Enterprises are increasingly adopting a multicloud approach, which involves utilizing various IaaS providers, to reduce risk and take advantage of competitive pricing.
- DevOps tooling, such as Git, Jira, SonarQube, and Gradle, are essential for managing source code, tracking issues, automating builds, and ensuring code quality in the cloud environment.
- Git is a distributed source code management and version control system used for tracking development progress and managing branches.
- Jira is an issue and project tracking platform for managing project progress, creating branches, pull requests, and automating tasks.
- SonarQube is a free code review tool for static code analysis and bug detection in multiple programming languages.
- Gradle is a multi-language build automation tool for managing dependencies and building applications with support for Java, C++, and Python, among others.
