Notably on this dawning period of generative AI, cloud prices are at an all-time excessive. However that’s not merely as a result of enterprises are utilizing extra compute — they’re not utilizing it effectively. In actual fact, simply this yr, enterprises are anticipated to waste $44.5 billion on pointless cloud spending.
That is an amplified downside for Akamai Applied sciences: The corporate has a big and sophisticated cloud infrastructure on a number of clouds, to not point out quite a few strict safety necessities.
To resolve this, the cybersecurity and content material supply supplier turned to the Kubernetes automation platform Solid AI, whose AI brokers assist optimize value, safety and pace throughout cloud environments.
In the end, the platform helped Akamai lower between 40% to 70% of cloud prices, relying on workload.
“We would have liked a steady technique to optimize our infrastructure and cut back our cloud prices with out sacrificing efficiency,” Dekel Shavit, senior director of cloud engineering at Akamai, instructed VentureBeat. “We’re those processing safety occasions. Delay just isn’t an choice. If we’re not in a position to reply to a safety assault in actual time, we now have failed.”
Specialised brokers that monitor, analyze and act
Kubernetes manages the infrastructure that runs functions, making it simpler to deploy, scale and handle them, notably in cloud-native and microservices architectures.
Solid AI has built-in into the Kubernetes ecosystem to assist prospects scale their clusters and workloads, choose the very best infrastructure and handle compute lifecycles, defined founder and CEO Laurent Gil. Its core platform is Utility Efficiency Automation (APA), which operates by a workforce of specialised brokers that constantly monitor, analyze and take motion to enhance utility efficiency, safety, effectivity and value. Corporations provision solely the compute they want from AWS, Microsoft, Google or others.
APA is powered by a number of machine studying (ML) fashions with reinforcement studying (RL) based mostly on historic knowledge and realized patterns, enhanced by an observability stack and heuristics. It’s coupled with infrastructure-as-code (IaC) instruments on a number of clouds, making it a totally automated platform.
Gil defined that APA was constructed on the tenet that observability is simply a place to begin; as he referred to as it, observability is “the muse, not the purpose.” Solid AI additionally helps incremental adoption, so prospects don’t have to tear out and substitute; they will combine into current instruments and workflows. Additional, nothing ever leaves buyer infrastructure; all evaluation and actions happen inside their devoted Kubernetes clusters, offering extra safety and management.
Gil additionally emphasised the significance of human-centricity. “Automation enhances human decision-making,” he mentioned, with APA sustaining human-in-the-middle workflows.
Akamai’s distinctive challenges
Shavit defined that Akamai’s massive and sophisticated cloud infrastructure powers content material supply community (CDN) and cybersecurity companies delivered to “a number of the world’s most demanding prospects and industries” whereas complying with strict service degree agreements (SLAs) and efficiency necessities.
He famous that for a number of the companies they eat, they’re most likely the biggest prospects for his or her vendor, including that they’ve performed “tons of core engineering and reengineering” with their hyperscaler to assist their wants.
Additional, Akamai serves prospects of varied sizes and industries, together with massive monetary establishments and bank card corporations. The corporate’s companies are immediately associated to its prospects’ safety posture.
In the end, Akamai wanted to steadiness all this complexity with value. Shavit famous that real-life assaults on prospects might drive capability 100X or 1,000X on particular elements of its infrastructure. However “scaling our cloud capability by 1,000X upfront simply isn’t financially possible,” he mentioned.
His workforce thought of optimizing on the code aspect, however the inherent complexity of their enterprise mannequin required specializing in the core infrastructure itself.
Robotically optimizing all the Kubernetes infrastructure
What Akamai actually wanted was a Kubernetes automation platform that would optimize the prices of operating its whole core infrastructure in actual time on a number of clouds, Shavit defined, and scale functions up and down based mostly on continually altering demand. However all this needed to be performed with out sacrificing utility efficiency.
Earlier than implementing Solid, Shavit famous that Akamai’s DevOps workforce manually tuned all its Kubernetes workloads only a few instances a month. Given the size and complexity of its infrastructure, it was difficult and dear. By solely analyzing workloads sporadically, they clearly missed any real-time optimization potential.
“Now, lots of of Solid brokers do the identical tuning, besides they do it each second of on daily basis,” mentioned Shavit.
The core APA options Akamai makes use of are autoscaling, in-depth Kubernetes automation with bin packing (minimizing the variety of bins used), computerized choice of probably the most cost-efficient compute situations, workload rightsizing, Spot occasion automation all through all the occasion lifecycle and value analytics capabilities.
“We obtained perception into value analytics two minutes into the mixing, which is one thing we’d by no means seen earlier than,” mentioned Shavit. “As soon as lively brokers have been deployed, the optimization kicked in robotically, and the financial savings began to return in.”
Spot situations — the place enterprises can entry unused cloud capability at discounted costs — clearly made enterprise sense, however they turned out to be sophisticated as a consequence of Akamai’s complicated workloads, notably Apache Spark, Shavit famous. This meant they wanted to both overengineer workloads or put extra working fingers on them, which turned out to be financially counterintuitive.
With Solid AI, they have been in a position to make use of spot situations on Spark with “zero funding” from the engineering workforce or operations. The worth of spot situations was “tremendous clear”; they simply wanted to search out the appropriate instrument to have the ability to use them. This was one of many causes they moved ahead with Solid, Shavit famous.
Whereas saving 2X or 3X on their cloud invoice is nice, Shavit identified that automation with out handbook intervention is “priceless.” It has resulted in “huge” time financial savings.
Earlier than implementing Solid AI, his workforce was “continually shifting round knobs and switches” to make sure that their manufacturing environments and prospects have been as much as par with the service they wanted to put money into.
“Palms down the largest profit has been the truth that we don’t must handle our infrastructure anymore,” mentioned Shavit. “The workforce of Solid’s brokers is now doing this for us. That has freed our workforce as much as give attention to what issues most: Releasing options quicker to our prospects.”
