Delivering Immutable Applications In consistent application deployment, the over-arching goal is to deliver an artifact bundled with it’s dependencies in a way that discourages modification. When performed in a manner that is quick and easily repeated, you can effectively increase development velocity through faster iterations. Effectively, you will put yourself on the right path to building and delivering a Twelve-Factor app! In traditional methods of application deployment, we would provision servers with necessary dependencies before shipping the application itself. In general, this works fine for a new server. However, what happens when we need to upgrade a dependency on that machine for a new version of the application? Problems …show more content…
However, building a new image and swapping the old one out can easily take an hour or more. Luckily we can employ containers, with the assistance of Docker, to help elegantly solve this issue. Containerization Containers allow us to build a unit to house our application and all of it’s dependencies in an inherently immutable format. This provides us with a consistent deployment unit, capable of being injected into any server and behaving the exact same, regardless of its coded environment. Now that we have an immutable, self-contained artifact requiring no packages or libraries for server installation, we can discuss branching strategies. In the spirit of immutability, it’s in our best interest to build this artifact only once priory to emplacing it in our various environments. In contrast, the popular Gitflow pattern seen here would dictate that we build separate artifacts, based on branch merges, for all of our environments. This does not align with our goals, however, as it introduces a point of potential change. We want to build once and deploy everywhere, handling configuration through environment variables. What About Hotfixes? Though it may hinder immutability when building artifacts, Gitflow can still be a valuable tool for making improvements to hotfixes. When your production environment has its own version control branch (usually master), it’s simple to make a commit to that branch with the hotfix, thereby alleviating any concerns over deploying it with
Containers hold the components necessary to run the desired software, such as files, environment variables, and libraries. The host OS also constrains the container's access to physical resources – such as CPU and memory – so a single container cannot misbehave and consume all of a host's physical
Solutions will focus on dependency abstraction and flexibility to alter or replace various layers of the delivery “stack” without locking USPTO into technologies or services that become untenable. Adopting the “Hybrid Cloud” paradigm will advance the future state and simplify service management. Some accomplishments are :
I believe my contributions as an individual stand out as a strong candidate for admission to a UC because I value my success in my education, together with my personal life. I have always wanted to make my parents and my family proud since I am the oldest; it has been their dream to see me attend a UC and graduate from one. As a UC student, I will strive to dedicate all of my efforts and do my very best in the educational work that I do on campus, on top of what I can bring on and off campus. I have a strong dedication for my passions, and unique talents that would serve as a fitting quality for a UC student. I am most passionate to do the best that I can in anything when I am given the opportunity. I am willing to go out of my way to help others out before I help myself, because I find it important that others around me must be happy and feel positive, especially if they are my friends.
* How will applications be deployed? If using Group Policy, what are the details on how Group Policy will be used to deploy the software? Which software applications will likely be needed?
The deployment of software can be a very drooling task at times. Other times it is as simple as starting an executable file and advancing through a variety of options. For most computer owners this is not a huge issue, however in large operations where more than 100 computers are on an extended network it can be a rather pressing problem. In the local
DevOps challenge is to map between development and operation. The main challenge her is both of development and operation have a different environment. Whereas Development environment is changing environment, production environment is stable. The major challenge here is to deliver changes in stable environment without any kind of interruption. The key solution for this challenge is continuous integration [2].
The classical software development process does not support reuse.[2] Reusable assets should be designed and built in a clearly defined, open way, with concise interface specifications, understandable documentation, and an eye towards future use. Typically, customer, client, and contract projects are built as "one-time only," without reuse in mind, and tend to be tightly bound within themselves, without the more robust open interfaces which ease the reuse process. Therefore, in order to make the most of software reuse, the software development process must evolve to include reuse activities.

The features of containers depend highly on how much the container have been configured and on which Linux-based container is currently being used, as Linux-based containers will be implemented differently in projects. (Rami Rosen, (2012), Linux Containers and the Future Cloud 2014 Page 2) A user may create a container by using ready-made templates. In lxc-0.9, there are 11 such templates, mainly for the most commonly used Linux distributions. These may be modified to accommodate the needed requirements. (Rami Rosen, (2014). Linux Containers
In the past applications were monolithic, and built on a single stack such as .Net or Java and ran on a single server. There is no way to get around building distributed software in today’s market. Just think about the software out there today. The market consist of many different variations of architecture tier an application may have such as an UI tier, caching tier, application tier, and persistence tier such as SQL or table logging.
A successful deployment makes your software more accessible to others and protects it from piracy. However, the deployment phase takes a lot of time to complete and takes developer’s efforts away from what is most important: Creating the best product possible. Hence, application deployment software is a crucial phase of the development process. Software deployment programs like Windows deployment toolkits make it possible to automate the deployment process. Automating the process saves time, increases production efficiency and reduces the chances of human error. There are many software deployment tools to choose from, but we selected the five
Dynamic applications can be built and orchestrated using containers to be highly scalable and resilient. Edge-LB’s templates make it possible to update, scale and automatically recover applications without disrupting traffic to and from the outside world.
As distributed environments have become the norm for software development, coordinating the efforts of development teams has become one of the biggest challenges faced by the enterprise today. It is hard to imagine any sizable development project managed without an underlying software configuration management tool.Teams situated at different geographical locations, including offshore, collaborate using communication technologies to develop interrelated software modules that are integrated in shared project workspaces. The software design process involves many iterative cycles of development
Basically, the more an organization can abstract infrastructure management, thus hiding its complexity from developers, the better that development team can decompose its applications into individual services while retaining a sense of the application’s complete scope and purpose, thus dramatically improving the organization’s velocity. No longer do application developers have to manage servers, the OS, containers, security, scheduling management, or myriad other functions that can and should be
