Accelerating Time-to-Value Through Hybrid Cloud Automation
- 1. Digital Systems & Technology Accelerating Time-to-Value Through Hybrid Cloud Automation Reusable design patterns and automated workflows can cut costs and speed deployment. Here’s how to get started. Executive Summary In search of lower costs and greater operational agility, businesses are hosting ever more workloads on virtualized compute, storage and network resources in the cloud. By 2020 more than 90% of enterprises will use multiple cloud services and platforms, according to market researcher IDC. 1 More than half of those surveyed by cloud management software provider RightScale plan to use hybrid (public/private) clouds that can offer greater control and security for critical data or applications.2 But without the proper tools and processes, moving to the cloud can saddle the business with a sprawl of expensive, hard-to-manage and insecure assets. Getting the most value from a move to the hybrid cloud requires: ❙ Proper end-to-end provisioning of workloads across the enterprise to assure they are sized, priced and managed to fit the needs of the business. ❙ A common management platform to give the organization a comprehensive view of price, performance and security across cloud providers. ❙ Agile and automated provisioning of workloads using standard design patterns (organization approved configurations for platforms such as Web servers Cognizant 20-20 Insights September 2019

Manually performing all these functions for each cloud deployment can eliminate the very cost and agility benefits organizations hope to gain from this computing model. While public cloud services have automated much of their internal provisioning processes, they have failed to extend such automation to their customers’ systems and processes, or to workload migration and management across multiple public and hybrid clouds. In our work with leading enterprises, such “customer-side” automation have cut deployment times from weeks to hours, slashed total cost of ownership by as much as 40%, and provided cross- cloud monitoring and management through a single platform as well as a real-time dashboard that revealed the types, quality and cost of the cloud services users consume. This white paper describes how automating hybrid cloud migration and management can deliver lower costs and greater flexibility. This results in the following business benefits: ❙❙ High levels of automation and standardization across infrastructure as a service (IaaS) and platform as a service (PaaS) environments to significantly reduce infrastructure provisioning times. ❙❙ Average time to provision a new server can be reduced from as long as 12 weeks to as little as one hour for simple patterns and less than a day for more complex patterns, making new servers available more quickly and reducing the cost of provisioning and charging for them. ❙❙ Faster development and deployment cycles for products and services to increase organizational competitiveness. Finally, we provide actionable tips for getting started. Cognizant 20-20 Insights 2 / Accelerating Time-to-Value Through Hybrid Cloud Automation
- 3. Cognizant 20-20 Insights 3 / Accelerating Time-to-Value Through Hybrid Cloud Automation Where cloud automation falls short Leading public cloud providers have taken most of the manual work out of tapping their compute, network and storage resources. With a corporate credit card, any user can quickly create and use internet-based web, application or database instances, such as those needed for e-commerce or for DevOps (combining development and operations functions to speed applications and services to market) along with the storage and networks they require. Public clouds offer predetermined “T-shirt sizes” for commonly requested combinations of resources, as well as robust tools for defining and monitoring cloud workloads. For example, Google’s Cloud Deployment Manager lets customers specify the resources needed by an application using the YAML3 language to create configuration files. AWS CloudFormation provides a common language for describing and provisioning infrastructure resources in the cloud. Azure Monitor provides performance and utilization data, activity and diagnostics logs, and notifications from Microsoft’s public cloud platform. But such tools fail to automate much of the work businesses must perform in their own environments to make the most efficient use of the cloud. This includes integrating their internal systems and processes for authenticating users, securing assets, tracking expenses and monitoring system performance with hybrid clouds. Nor do public cloud providers make it easy to bring their own management functions to the hybrid clouds most enterprises are adopting. In addition, each provider’s automation tools are proprietary and do not easily interoperate with those used in other public clouds or in hybrid clouds. This means making use of multiple clouds or automating deployment across landing zones within a single cloud provider. These approaches require expensive integration efforts or entail managing multiple clouds through different user interfaces. Either path makes it much harder to get a holistic view of everything from cost to performance to security. This lack of automation imposes real costs on enterprises. RightScale survey of cloud users found that only a minority have implemented automated policies to optimize cloud costs, such as shutting down unused workloads or selecting lower-cost clouds or regions.4 Conversely, a lack of automation impacts organizational agility, potentially resulting in business disruption from competitors. Public clouds offer predetermined ‘T-shirt sizes’ for commonly requested combinations of resources, as well as robust tools for defining and monitoring cloud workloads.

Cognizant 20-20 Insights 4 / Accelerating Time-to-Value Through Hybrid Cloud Automation How automation can help Hybrid cloud customers can use automation in many ways to reduce costs and maximize agility. They can automate pre-provisioning workflows such as budgetary and security approvals, determining if a user has the right to access the requested resources and assuring the resources provisioned in the cloud meet all applicable business and technical requirements. They can also automate post-provisioning tasks, such as integrating the cloud with directories that track users and other assets, system monitoring, patching and accounting systems, and third- party security monitoring and penetration testing tools and services. To make the cloud as easy and inexpensive as possible to use, they can deliver cloud resources as an easy-to-consume item in their service catalog (see Figure 1). Each provider’s automation tools are proprietary and do not easily interoperate with those used in other public clouds or in hybrid clouds. This means making use of multiple clouds or automating deployment across landing zones within a single cloud provider.

Hybrid clouds can’t begin cutting your organization’s costs and increasing its agility until workloads are migrated and integrated with existing management, security and chargeback platforms and processes. 6 / Accelerating Time-to-Value Through Hybrid Cloud Automation Automation: Getting started Hybrid clouds can’t begin cutting your organization’s costs and increasing its agility until workloads are migrated and integrated with existing management, security and chargeback platforms and processes. Automating these processes requires understanding and meeting the full range of management, financial and security issues the cloud raises for customers. Based on our work with leading organizations worldwide, our recommendations for embracing automated hybrid cloud management include the following actions: ❙❙ Create reusable automated workflows for common processes such as approval and access control. ❙❙ Minimize the number of blueprints and canned images included in common cloud workloads to optimize management and governance overhead. This might involve, for example, limiting the number of Linus blueprints to include only RHEL, SUSE Linux and CentOS, and limiting Windows blueprints to Windows Server 2012 and 2016. Other required functions or features can be easily provisioned in a modular fashion on the base image. ❙❙ Use automated tools for provisioning and configuration of all management agents during the “post-provisioning” stage. For example, install monitoring, antivirus, backup and patching agents, and associated configuration activities, using a configuration management tool. Similarly, automate activities for service account creation, assigning permissions, etc. as part of the overall provisioning request itself. ❙❙ Create an efficient pipeline to reduce the time required to create, deploy and manage infrastructure as code. In a client situation, we used the GitHub code repository, the Jenkins open source automation server, Artifactory repository manager and the Puppet software configuration management tool that uses “infrastructure-as-a-code” principles to provision infrastructure in an agile fashion. ❙❙ Automate processes not only within your organization but with third parties such as cloud providers. For example, use API calls to integrate with third-party providers responsible for role-based access control and network provisioning. Cognizant 20-20 Insights

RightScale 2018. Cognizant 20-20 Insights Getting the most from the cloud Organizations move to elastic, on-demand cloud environments to cut costs and speed new products and services to market. But without proper automated tools and processes, they can find themselves spending too much money and time managing a mix of on-premise and public clouds. Automated workflows and standard system images not only cut management costs, but allow users to provision their own systems while meeting corporate cost, security and other requirements. 8 / Accelerating Time-to-Value Through Hybrid Cloud Automation
