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. The truth is, 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 price, safety and pace throughout cloud environments.
Finally, the platform helped Akamai reduce between 40% to 70% of cloud prices, relying on workload.
“We wanted a steady method to optimize our infrastructure and cut back our cloud prices with out sacrificing efficiency,” Dekel Shavit, senior director of cloud engineering at Akamai, advised VentureBeat. “We’re those processing safety occasions. Delay is just not an possibility. If we’re not in a position to reply to a safety assault in actual time, now we 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, significantly in cloud-native and microservices architectures.
Solid AI has built-in into the Kubernetes ecosystem to assist clients scale their clusters and workloads, choose the perfect infrastructure and handle compute lifecycles, defined founder and CEO Laurent Gil. Its core platform is Utility Efficiency Automation (APA), which operates by means of a workforce of specialised brokers that constantly monitor, analyze and take motion to enhance software efficiency, safety, effectivity and value. Firms 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 inspiration, not the aim.” Solid AI additionally helps incremental adoption, so clients don’t have to tear out and change; they’ll combine into present 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 stated, 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 providers delivered to “a few of the world’s most demanding clients and industries” whereas complying with strict service stage agreements (SLAs) and efficiency necessities.
He famous that for a few of the providers they eat, they’re most likely the most important clients for his or her vendor, including that they’ve carried out “tons of core engineering and reengineering” with their hyperscaler to help their wants.
Additional, Akamai serves clients of varied sizes and industries, together with massive monetary establishments and bank card firms. The corporate’s providers are instantly associated to its clients’ safety posture.
Finally, Akamai wanted to steadiness all this complexity with price. Shavit famous that real-life assaults on clients may drive capability 100X or 1,000X on particular parts of its infrastructure. However “scaling our cloud capability by 1,000X prematurely simply isn’t financially possible,” he stated.
His workforce thought-about optimizing on the code facet, however the inherent complexity of their enterprise mannequin required specializing in the core infrastructure itself.
Routinely optimizing the whole Kubernetes infrastructure
What Akamai actually wanted was a Kubernetes automation platform that would optimize the prices of operating its complete core infrastructure in actual time on a number of clouds, Shavit defined, and scale functions up and down based mostly on always altering demand. However all this needed to be carried out with out sacrificing software efficiency.
Earlier than implementing Solid, Shavit famous that Akamai’s DevOps workforce manually tuned all its Kubernetes workloads only a few occasions 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, a whole bunch of Solid brokers do the identical tuning, besides they do it each second of every single day,” stated Shavit.
The core APA options Akamai makes use of are autoscaling, in-depth Kubernetes automation with bin packing (minimizing the variety of bins used), automated number of essentially the most cost-efficient compute situations, workload rightsizing, Spot occasion automation all through the whole occasion lifecycle and value analytics capabilities.
“We acquired perception into price analytics two minutes into the mixing, which is one thing we’d by no means seen earlier than,” stated Shavit. “As soon as energetic brokers have been deployed, the optimization kicked in routinely, and the financial savings began to come back 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 result of Akamai’s complicated workloads, significantly Apache Spark, Shavit famous. This meant they wanted to both overengineer workloads or put extra working arms 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 only wanted to seek out the suitable device 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 guide intervention is “priceless.” It has resulted in “large” time financial savings.
Earlier than implementing Solid AI, his workforce was “always transferring round knobs and switches” to make sure that their manufacturing environments and clients have been as much as par with the service they wanted to spend money on.
“Palms down the most important profit has been the truth that we don’t must handle our infrastructure anymore,” stated Shavit. “The workforce of Solid’s brokers is now doing this for us. That has freed our workforce as much as deal with what issues most: Releasing options sooner to our clients.”
