In addition, DevOps and safety and provide cycles of rapid development and teams are at a very focused level now because they are distribution. Many of the ideas involved in DevOps come from responsible for automation and universal delivery and client business plan management and agile software development programming. This paper focuses on the automation of customer application from the provision of environment to the movements. DevOps goals cover all delivery pipelines.

  • Magic Quadrant for Application Release Automation
    Magic Quadrant for Application Release Automation Published: 27 September 2017 ID: G00315074 Analyst(s): Colin Fletcher, Laurie F. Wurster The ARA market is rapidly evolving in response to growing enterprise requirements to both scale DevOps initiatives and improve release management agility across multiple cultures, processes and generations of technology. This research helps I&O leaders make better-informed decisions. Strategic Planning Assumption By 2020, 50% of global enterprises will have implemented at least one application release automation solution, up from less than 15% today. Market Definition/Description Application release automation (ARA) tools provide a combination of automation, environment modeling and release coordination capabilities to simultaneously improve the quality and the velocity of application releases. ARA tools enable best practices in moving application-related artifacts, applications, configurations and even data together across the application life cycle process. These tools are a key part of enabling the DevOps goal of achieving continuous delivery with large numbers of rapid, small releases. Approximately seven years old, the ARA solution market reached an estimated $228.2 million in 2016, up 31.4% from $173.6 million in 2015. The market is continues to be expected to grow at an estimated 20% compound annual growth rate (CAGR) through 2020. Magic Quadrant Figure 1.

  • CI-CD-For-Infrastructure-Configuration
    Abstract & Overview Organizations of all sizes, from the leanest startup to the stodgiest enterprise, use CI/CD practices to greatly improve production and delivery of software. This yields higher- quality software at a lower cost and allows businesses to deliver ideas to market faster. As development teams adopt CI/CD practices, they start delivering new applications and releases faster and faster. This constantly changing software inevitably requires changes to infrastructure and configuration, but many operations teams aren’t accustomed to the pace—nor do they have the proper tools required. Trying to directly apply successful CI/CD practices for applications is highly unlikely to yield success for infrastructure and configuration changes. In this guide, we explore: • How and why CI/CD has been so successful for application changes • Infrastructure and configuration changes as a new bottleneck • Challenges with CI/CD for infrastructure and configuration changes • How to overcome challenges and implement CI/CD for infrastructure We include a hands-on guide for how to implement this with BuildMaster and Otter. You can do everything in this guide with BuildMaster Free and Otter Free editions! About Inedo, Otter, and BuildMaster We help organizations make the most of their Windows technology and infrastructure through our Windows-native and cross-platform DevOps tools. • BuildMaster, a tool designed to implement CI/CD, automates application releases. • Otter manages infrastructure. Harnessing the power of both tools allows users to manage infrastructure while enjoying all the benefits of CI/CD.

With Broad network access advances in cloud technology, on demand cloud services Resource pooling offered by public providers are becoming gradually powerful, Rapid elasticity and Measured service anchoring the ecosystem of cloud services. Moreover, the DevOps teams are in much bigger focus now since they are responsible for the automation and provisioning of the whole 1.3 Introduction to Cloud Service Models environment along with the client application. This paper focuses upon the automation of customer application right from environment provisioning to application deployment. According to a white paper by Vision Solutions, 59% of Fortune 500 companies experienced a minimum of 1.6 hours of downtime per week. This means that for a company who has 10,000 employees who on average make a salary of $30 per hour, or $60,000 per year, this downtime can potentially create a loss of $480,000 weekly or nearly 25 million dollars annually, not including the cost of benefits, loss of sales, or negative impact to the reputation of the provider from services being unavailable. Therefore, it is of the utmost importance for a company’s servers to have their services installed, configured, and running as quickly as possible and as consistent as possible to help reduce costs. This translates into automated deployment and configuration.

    Your Trusted Technology Partner www.goavega.com ABSTRACT In this modern landscape, most businesses struggle to evolve innovatively with ever-changing customer needs. Time is a very crucial factor in this process and to hit the mark, both the IT departments and business goals need to be highly agile. The digital industry has witnessed the software development lifecycles making a shift from the waterfall to Agile models of development that increase the overall efficiency. And all thanks to the evolution of DevOps that these improvements are smoothly adapting IT operations. DevOps-oriented teams take 21% less time to put out fires per week in comparison with traditional IT Ops teams. Automation and the modern cloud structure are the keys to fulfilling the demands of agile businesses but to get there, one must deploy IT operations consistently and reliably manner repeated over and over again. DEFINING DEVOPS Source DevOps is a collective combination of IT operations and software development that helps you shorten the development life cycle of a system and opens gates to delivering high-quality software. Since many aspects of DevOps find their origination in Agile methodology, it is often introduced as complementary with Agile software development. In short, it is the practice using which we optimize development and operational activities backed with a well-structured process. With that being said, DevOps-oriented teams spend 33% more time improving infrastructure against failures as compared to traditional IT Ops teams. Stakeholders in any delivery process need to collaborate to be essential to customers. Similarly, development teams are expected to design, develop, and deliver perfectly 2 | DevOps for the Modern Cloud running software as soon as possible and that too in a reliable manner.
