MIST 4630 FINAL EXAM QUESTIONS &
COMPLETE SOLUTIONS
Container - ANSWERin software, this is a standard unit of software that packages up
code and all its dependencies so the application runs quickly and reliably from one
computing environment to another
container image - ANSWERa lightweight, stand-alone, executable software package
that includes everything you need to run a piece of software: the code, a runtime,
libraries, environment variables, and config files.
how are containers used in software development? - ANSWERthey isolate software
from its surroundings, for instance, differences between development and staging
environments, and to help reduce conflict between teams running different software on
the same infrastructure
containers are designed to be portable and consistent across environments, which is a
key advantage in DevOps and cloud-native applications.
advantages of containers - ANSWER1. consistency and portability:
containers ensure that applications run smoothly across different environments (ex:
development, testing, and production) because they all include major dependencies
2. microservices architecture
3. resources efficiency
containers are more efficient than traditional virtual machines. they share the host
system's OS kernel, rather than needing their own operating system. This results in
faster start-up times and better utilization of underlying resources.
4. isolation
containers isolate applications and their dependencies from one another, which
improves security by reducing the attacking surface and enhances productivity by
reducing conflict between teams working on different software stacks.
5. rapid development and scaling
containers can be stopped, started, and scaled rapidly, which is essential for modern
development
6. DevOps and agile development
containers support DevOps initiatives by promoting continuous integration integration
and continuous deployment (CI/CD). This accelerates development cycles and helps in
faster release of applications.
7. applications versioning and rollback
containers simplify application versioning and rollback, making it easier to convert to
new versions or revert to old versions
8. either debugging or maintenance
containers help in replicating production environments locally, locally, which makes
debugging easier. also encourage module design with simpler maintenance.
9. infrastructure optimization
, containers help in optimizing infrastructure resources as they allow running multiple
applications on the same hardware, reducing infrastructure costs.
10. rich ecosystem:
The rich ecosystem of tools and communities around container technologies like Docker
and Kubernetes provides a vast range of solutions for common development and
operational challenges.
what is docker? - ANSWERdocker is a platform that utilizes containerization technology
to package, distribute, and run applications in a consistent environment
how is docker used to implement containers? - ANSWERdocker provides a platform for
developers and system administrators to develop, deploy, and run applications with
containers. This ensures that the software runs reliably when moved from one
computing environment to another. Docker enables the creation of container images
which are lightweight, standalone, executable software packages. These images
include everything required to run the application. Although docker was initially a tool for
containerization it now integrates with container orchestration tools like Kubernetes or
Docker Swarm, which help in deploying, scaling, and managing containerized
applications. Docker provides a registry service called Docker Hub for sharing and
managing container images. This facilitates the distribution of applications across
various environments and also allows for version control and component reuse. Docker
helps ensure that applications run consistently across various development, testing, and
production environments, which in term improves development efficiency. Docker
containers isolate applications from each other and the underlying infrastructure,
ensuring software reliability and promoting portability. Docker has robust community
and ecosystem that contributes to its library and help in developing container-based
solutions. Docker has become synonymous with container technology due to its early
and significant impact in this domain, making it easier for developers to create, deploy,
and run applications by using containers.
Kubernetes simplifies many aspects of running containerized applications at scale,
making it a cornerstone in modern cloud-native ecosystem. It complements container
applications like Docker by adding a higher level of abstraction, which is orchestration
and management of containerized microservices and applications - ANSWERyay
Benefits of Kubernetes - ANSWER1. flexibility to scale quickly with business demand
2. portability to run anywhere
3. high availability through self-healing
4. cost optimization
5. multi-cloud
what is docker? - ANSWERDocker uses images and containers to allow apps to run
anywhere constantly.
container facts - ANSWER1. do not emulate any hardware and do not need to "boot up"
