Cloud Infrastructure and DevOps are two intertwined concepts that have revolutionized the tech industry. This glossary entry aims to dissect these concepts, providing a comprehensive understanding of their definitions, history, use cases, and specific examples.
Cloud Infrastructure refers to the hardware and software components, such as servers, storage, a network, and virtualization software, that are needed to support the computing requirements of a cloud computing model. DevOps, on the other hand, is a set of practices that combines software development (Dev) and IT operations (Ops), with the goal of shortening the systems development life cycle and providing continuous delivery with high software quality.
Definition
Cloud Infrastructure is the collection of hardware and software that enables the five essential characteristics of cloud computing. The cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability.
DevOps is a set of practices that automates the processes between software development and IT teams, in order that they can build, test, and release software faster and more reliably. The concept of DevOps is founded on building a culture of collaboration between teams that historically functioned in relative siloes.
Cloud Infrastructure Components
The main components of cloud infrastructure are: Compute, Storage, Networking, and Virtualization. Compute power is the core component of cloud infrastructure. It is the computational resources needed for processing tasks. Storage in cloud infrastructure refers to the data storage elements where you store information. Networking in the cloud infrastructure is the backbone that connects the cloud services externally to users and internally to other services. Virtualization is the creation of a virtual version of something, such as a server, a desktop, a storage device, an operating system or network resources.
You can manage these components directly or through a cloud service provider. The cloud service provider is responsible for the upkeep, maintenance and security of the cloud.
DevOps Practices
DevOps practices include continuous integration, continuous delivery, microservices, infrastructure as code, monitoring and logging, and communication and collaboration. Continuous integration is a coding philosophy and set of practices that drive development teams to implement small changes and check in code to version control repositories frequently. Continuous delivery is a software development practice where code changes are automatically built, tested, and prepared for a release to production.
Microservices is an architectural style that structures an application as a collection of services that are highly maintainable and testable, loosely coupled, independently deployable, organized around business capabilities, and owned by a small team. Infrastructure as code is a type of IT infrastructure that operations teams can automatically manage and provision through code, rather than using a manual process. Monitoring and logging helps to track the performance of applications, identify issues, and gather insights about how applications and systems are performing. Communication and collaboration are key practices in DevOps, as they foster a culture of transparency and sharing across teams.
History
The concept of cloud computing dates back to the 1960s, when computer bureaus would allow companies to rent time on a mainframe, rather than have to buy one themselves. The term "cloud" was inspired by the symbol that network engineers would draw to represent the demarcation point between that which was the responsibility of the provider and that which was the responsibility of the user.
The term DevOps originated from a combination of terms for “development” and “operations”. Patrick Debois, a Belgian IT consultant, is often credited with creating the term DevOps. He wanted to come up with a solution to the common problem of software development and IT operations teams working in silos, leading to inefficiency and a lack of ownership. The term DevOps was popularized through a series of "devopsdays" starting in 2009 in Belgium.
Evolution of Cloud Infrastructure
Cloud infrastructure has evolved from simple data storage to now offering a comprehensive suite of services that can replace entire IT departments. The evolution of cloud infrastructure is closely tied to the development of the internet. The first milestone in the evolution of cloud computing was the arrival of Salesforce.com in 1999, which pioneered the concept of delivering enterprise applications via a simple website. The next development was Amazon Web Services in 2002, which provided a suite of cloud-based services including storage, computation and even human intelligence.
The most significant event in cloud infrastructure history was the launch of Amazon’s Elastic Compute Cloud (EC2) in 2006. EC2 allowed users to rent virtual computers on which to run their own computer applications. This was the first time that small companies had access to the kind of scale that previously only large companies could afford.
Evolution of DevOps
The evolution of DevOps is a result of many years of fine-tuning the software development process. In the past, the development and operations teams had separate roles and responsibilities. However, this separation often led to challenges such as miscommunication, delayed production times, and a lack of ownership. The introduction of Agile development in 2001, with its emphasis on collaboration, customer feedback, and small, rapid changes, set the stage for the evolution of DevOps.
The first major milestone in the DevOps movement was the creation of the Agile System Administration group in 2007, which was later renamed to the Agile Operations group. The group aimed to apply Agile principles to system administration. The term "DevOps" was coined in 2009 by Patrick Debois, who was one of the members of the Agile Operations group. The concept of DevOps was further popularized by a number of DevOpsDays conferences held worldwide since 2009.
Use Cases
Cloud Infrastructure and DevOps have a wide range of use cases across various industries. They are used to streamline business processes, reduce costs, increase efficiency, and improve the quality of products or services.
Cloud Infrastructure is commonly used for data backup, disaster recovery, email, virtual desktops, software development and testing, big data analytics, and customer-facing web applications. DevOps, on the other hand, is used to accelerate software delivery, improve delivery predictability, increase the quality of the software product, and improve the productivity of the software team.
Cloud Infrastructure Use Cases
One of the most common use cases for cloud infrastructure is data backup and disaster recovery. Companies can store their data in the cloud, which can be accessed anytime, anywhere, and from any device. This not only provides a cost-effective solution for data storage, but also ensures that the data is safe and secure. In case of a disaster, companies can quickly recover their data from the cloud, minimizing downtime and loss of productivity.
Another use case for cloud infrastructure is in the development and testing of software. Developers can quickly set up and dismantle test environments in the cloud, saving time and resources. This also allows for testing under different operating environments and conditions. Furthermore, cloud infrastructure can be used for big data analytics. Companies can store and analyze large amounts of data in the cloud, gaining insights that can help in making informed business decisions.
DevOps Use Cases
One of the key use cases of DevOps is in accelerating software delivery. By fostering a culture of collaboration and implementing practices such as continuous integration and continuous delivery, DevOps enables faster development and deployment of software. This not only reduces the time to market, but also allows for quicker feedback and iterations.
Another use case of DevOps is in improving the quality of the software product. Through practices such as automated testing, continuous integration, and infrastructure as code, DevOps helps in catching bugs and issues early in the development process, leading to a higher quality product. DevOps also improves the productivity of the software team by automating repetitive tasks, freeing up the team to focus on more strategic tasks.
