Cloud adoption is undoubtedly the cornerstone of digital transformation, and for many, it is the foundation for rapid, scalable application development and delivery. Companies of all sizes and from across all industries are racing to achieve the many benefits afforded by public, private or hybrid cloud infrastructure. According to a recent study, 20 percent of enterprises plan to more than double public cloud spending in 2018, and 71 percent will grow public cloud spending more than 20 percent.\nEnterprises moving to the cloud are often seeking to improve employee collaboration, ensure redundancy, boost security and increase agility in application development. One of the top advantages afforded by the cloud is the ability to auto-scale in response to demand \u2014 a feature that has transformed what was once capacity planning into a more continuous cycle of capacity and resource management.\nThe impact of the cloud\nWhen it comes to physical data centers, capacity planning primarily entails predicting, purchasing and installing the maximum number of servers an organization may need. As traffic needs change over time, data centers can be expanded or consolidated, but changes are slow and cumbersome. Capacity must be able to accommodate brief spikes in traffic, otherwise performance and uptime are negatively impacted. Software engineers must be, in effect, \u201cmagicians\u201d who use predictive modeling matching application needs and traffic drivers to resource constraints in order to determine the correct capacity. While planning tools can be beneficial, the complexity of this setup causes most to take the \u201cwait until it breaks\u201d approach to determine what the upper limits are.\nWith cloud computing, a burst of traffic can be more easily addressed as modern enterprises can quickly spin up new services and capacity to dramatically improve user experiences. This flexibility allows organizations to account for both expected spikes or unexpected conditions, such as the historically well-known \u201cSlashdot\u201d effect. Whether it is predictable or not, we can now build applications to respond to events because of the automation and flexibility enabled by the cloud. This idea of \u201cinfinite\u201d capacity and elastic infrastructure is appealing, and devops processes and tools like Terraform have improved the speed at which scale is possible. At NS1, for example, our team has built what is essentially a push-button operation to stand up a new cloud deployment of our entire platform, from scratch. This process \u2014 which previously would have taken weeks or months \u2014 has been reduced to a matter of minutes.\nMany cloud providers offer tools, such as AWS CloudFormation, that automate and deploy additional resources in a repeatable manner. Based on predetermined specifications, these tools will provision and configure new stacks and resources from a template. But the process is restricted to the service provider and more locally driven, which can limit usefulness.\nData-driven resource management\nOrganizations are moving increasingly to the edge, leveraging hybrid and multi-cloud approaches, and their widely distributed and dynamic infrastructures are changing constantly. As a result, resource management has become a continuous effort that requires a global view into capacity and performance, not merely a myopic view into one region or cloud instance. Real-time analytics, measured against real application metrics, give IT teams the insight needed to deploy new infrastructure and manage the use of resources to address performance issues, application needs, unexpected traffic spikes or even to control costs between cloud providers. Data can be used to balance loads between resources based on actual conditions or even to rapidly spin up new cloud instances to increase capacity in strategic geographic locations to essentially \u201cfollow the sun,\u201d or move infrastructure around based on demand so that processing is occurring at the edge. Advanced teams also leverage network performance data for additional insights that drive resource management. Additional cloud instances can be deployed in locations when and where internet conditions are chronically slow or unpredictable.\nThe future of cloud and resource management\nAs more enterprises embrace hybrid and multi-cloud approaches and infrastructure becomes increasingly distributed and dynamic, the demand for tools that provide a vendor-agnostic, global view of existing internal and external conditions will increase. More organizations will begin correlating data from measurement tools that provide real-time visibility to automated decision making and tools programmed to redeploy resources to address demand. Continuous resource planning will become an essential part of IT operations.
