Cloud providers aim to take away the trouble of the brick and mortar of physical equipment. Utilizing the cloud can help companies increase efficiency and improve cash flow. Many companies have adopted cloud solutions in their operations in the past few years. Large amounts of money are spent developing and installing software to improve their competitive advantage. Cloud computing enables businesses to utilize software on the internet as a service. The proposed project will examine and explore multiple ways to configuring cloud infrastructure in Amazon Web Services. Infrastructure as code has been an emerging trend. Each with different strengths and weaknesses. The choices and adaptability of code as infrastructure has grown tremendously along with cloud services. As the popularity of cloud services grow, the demand of infrastructure as code has grown with it. iv TABLE OF CONTENTS SIGNATURE PAGE

viii CHAPTER 1 INTRODUCTION Technology has become a necessity of today’s generation. The demand for the advancement of technology has pushed companies to release more often to stay competitive. Many companies face challenges in scaling because they simply do not have the required resources and time to do it properly. Those issues are the reasons cloud providers were born. Companies has turned to cloud service providers to maintain their competitive advantage. A cloud service provider is a third-party company offering cloud-based platform, infrastructure, application, and or storage services. A way to visualize the role of a cloud provider would be a homeowner would pay for utilities such as electricity or water and would only pay usage consumption each month. Similarly, companies pay cloud providers for the usage. Cloud providers are based on the pay-per-used model. Companies can grow without worrying about

  • INFRASTRUCTURE AS CODE–FINAL REPORT John Klein, Phd and Douglas Reynolds December 2018
    INFRASTRUCTURE AS CODE–FINAL REPORT John Klein, PhD and Douglas Reynolds December 2018 1 Introduction This report concludes work on Research Project 6-18 518 Feasibility of Infrastructure as Code, summarizing the problem addressed by the research, the research solution approach, and results. 1.1 Background 1.1.1 What Is Infrastructure as Code? Infrastructure as code (IaC) is a set of practices that use “code (rather than manual commands) for setting up (virtual) machines and networks, installing packages, and configuring the environment for the application of interest” [3]. The infrastructure managed by this code includes both physical equipment (“bare metal”) and virtual machines, containers, and software-defined networks. This code should be developed and managed using the same processes as any other software; for example, it should be designed, tested, and stored in a version-controlled repository. Although information technology (IT) system operators have long employed automation through ad hoc scripting of tasks, IaC technology and practices emerged with the introduction of cloud computing, and particularly infrastructure-as-a-service (IaaS) technology. In an IaaS-based envi- ronment, all computation, storage, and network resources are virtualized and must be allocated and configured using application programming interfaces (APIs). While cloud service providers furnish management consoles that layer an interactive application on top of the APIs, it is not practical to use a management console to create a system with more than a couple of nodes. For example, creating a new virtual machine (VM) using the Amazon Web Services management console requires stepping through at least five web forms and filling in 25 or more fields.

    Cloud Programming Simplified: A Berkeley View on Serverless Computing Eric Jonas Johann Schleier-Smith Vikram Sreekanti Chia-Che Tsai Anurag Khandelwal Qifan Pu Vaishaal Shankar Joao Carreira Karl Krauth Neeraja Yadwadkar Joseph E. Gonzalez Raluca Ada Popa Ion Stoica David A. Patterson UC Berkeley [email protected] Abstract Serverless cloud computing handles virtually all the system administration operations needed to make it easier for programmers to use the cloud. It provides an interface that greatly simplifies cloud programming, and represents an evolution that parallels the transition from assembly language to high-level programming languages. This paper gives a quick history of cloud computing, including an accounting of the predictions of the 2009 Berkeley View of Cloud Computing paper, explains the motivation for serverless computing, describes applications that stretch the current limits of serverless, and then lists obstacles and research opportunities required for serverless computing to fulfill its full potential. Just as the 2009 paper identified challenges for the cloud and predicted they would be addressed and that cloud use would accelerate, we predict these issues are solvable and that serverless computing will grow to dominate the future of cloud computing.
