I think we can all agree that cloud-scale technologies are wonderful things, enabling hyper-agile delivery of applications and services to billions of users worldwide. Software-defined networking, virtualization, microservices, containers, open source software and Open Compute platforms are enabling cloud service providers to achieve mind-boggling economies of scale while keeping pace with insatiable user demand.
However, as telecom service providers and large-scale enterprises move to embrace cloud-scale technologies, they are proving to be both a blessing and a curse. The benefits are straightforward: rapidly deliver a broader range of applications and services at lower cost while being able to quickly respond to changing customer needs. The downside is that both service providers and enterprises need to employ new toolsets for developing, deploying and managing these applications and services.
Disaggregation and decomposition are consistent themes for cloud-scale technology. Monolithic platforms are separated into a software-driven control plane running on commodity hardware platforms. Network functions and computing resources are virtualized and decoupled from the underlying hardware. Monolithic applications are decomposed into many microservices that each run in their own container. The business value in terms of lower hardware costs coupled with increased flexibility and agility is real, but there are added costs associated with managing all these different piece parts.
The problem becomes obvious when service providers and enterprises try to apply existing management tools and methodologies to cloud-scale infrastructure. For all their internal complexity, configuring, monitoring and controlling monolithic platforms and applications is simpler than managing multiple layers of many different software components running on virtualized infrastructure. While the industry has recently made great strides by adopting new tools for cloud-scale infrastructure configuration and orchestration, we are still playing catch-up in terms of equally effective approaches to cloud-scale visibility and analytics.
Yet here is where cloud-scale technologies come to their own rescue. By disaggregating and decomposing software and hardware functions, with the proper instrumentation implemented at each layer and in every component, we are able to gain full visibility into the entire stack from top to bottom, while utilizing new technologies like streaming telemetry to provide extremely granular, real-time visibility into the application and service delivery infrastructure.
Therefore, it’s only natural that cloud-scale visibility and analytics should be implemented on native cloud-scale platforms, leveraging the same technologies: software-defined networking, virtualization, microservices, containers, open source software and Open Compute platforms. This is especially critical when employing Big Data analytics, where the basic technologies are inherently cloud-scale, and well-suited for ingesting Big Data streaming telemetry feeds and performing real-time streaming analytics on this data.
