Some numbers are hard to picture until you sit with them for a moment. Last week we published the Prime Day 2026 metrics, and the one that stuck with me is 2.3 quadrillion: the daily requests Amazon ElastiCache peaked at during the event. Prime Day ran back in June, so this post always lands as a retrospective, and that gap is part of what makes it worth reading. By the time the numbers reach you, the only evidence that any of it happened is that nothing went wrong.

The rest of the week pulled in a different direction: smaller, cheaper, and more constrained. Claude Haiku 5.5 arrived on Amazon Bedrock at roughly 75 percent less than Haiku 4.5, Amazon Nova 2.5 Sonic made voice agents quicker on their feet, and Strands Box showed up to put real boundaries around what an agent is allowed to do. Now, let’s get into this week’s AWS news…

Headlines
All the numbers: Amazon Prime Day 2026 powered by AWS is the latest entry in a tradition that goes back to 2016, and the scale is still difficult to hold in your head. Over the four days of Prime Day, Amazon DynamoDB processed more than 59 trillion requests while peaking at 192 million requests per second, and kept single-digit millisecond responses throughout. AWS Lambda handled over 2.3 trillion invocations per day. Amazon EBS peaked above 24.8 trillion I/O operations, moving more than an exabyte of data daily. Amazon ECS launched an average of 158.3 million tasks per day on AWS Fargate, a 47.7 percent jump over last year, and AWS Graviton powered up to 49 percent of the Amazon EC2 compute that Amazon.com used.

The number I keep coming back to, though, isn’t a throughput record. The team ran more than 44,000 AWS Fault Injection Service experiments ahead of the event, more than six times what they ran in 2025. Those are deliberate failures injected on purpose, months in advance, so that the trillions of requests above turn into an ordinary shopping afternoon. If you’re preparing for your own peak moment, AWS Countdown Premium is built for exactly that kind of planning.

Last week’s launches
Here are some launches and updates from this past week that caught my attention:

• Claude Haiku 5.5 is now available on AWS – You can now use the fastest model in the Claude 5.5 family on Amazon Bedrock and Claude Platform on AWS, at around 75 percent less than Claude Haiku 4.5 for most tasks. It’s the first Haiku with effort controls, so you can tune cost against intelligence per task instead of fixing one setting for a whole workload. It pairs naturally with Claude Opus 5.5: Opus plans and makes the judgment calls, and because Haiku is fast and cheap, you can run many Haiku subagents in parallel for routing, classification, and small code changes across many files.

• Amazon Nova 2.5 Sonic for voice agents – You can now build real-time voice agents on a speech-to-speech Amazon Nova model with better reasoning, instruction following, and tool-calling accuracy, plus lower latency. That combination matters for multi-step work: a support agent can look up an order, check return eligibility, and start the return inside one conversation. It keeps expressive voices in seven languages, controllable turn-taking, and a 256K context window, and pairs with Strands Bidi Agents, now generally available, to get a production voice agent going in a few lines of code.

• Amazon GuardDuty RDS Protection now detects data exfiltration and destruction – Amazon GuardDuty now looks past login anomalies to the queries themselves on Amazon Aurora PostgreSQL and Amazon RDS for PostgreSQL. RDS Protection for data activity builds behavioral baselines and uses ML-based anomaly detection plus threat intelligence to flag unusual data access, with no agents, extra infrastructure, or database configuration changes. This closes a real gap: once an attacker has valid credentials from phishing or a misconfiguration, their queries can look indistinguishable from your application’s.

• AWS Lambda supports OAuth for self-managed Apache Kafka event sources – You can now authenticate Lambda Kafka consumers through your enterprise identity provider, such as Amazon Cognito or Okta. Event source mappings previously supported only SASL/PLAIN, SASL/SCRAM, and mTLS, which left teams in regulated industries unable to use Kafka ESM at all. Now you get the automatic scaling, batching, error handling, and event filtering of Kafka ESM with the same identity governance you apply everywhere else. It works with self-hosted clusters and managed offerings including Confluent Cloud, Aiven, and Redpanda.

Other AWS news
Here are some additional posts and resources that you might find interesting:

• Introducing Strands Box: AI agent sandboxes powered by Dogwood – As more of us let agents run shell commands and call APIs without approving every step, isolation alone stops being enough. Strands Box is an open source sandbox (Apache 2.0, developer preview) that combines OS-level containment with fine-grained policies written in Dogwood, so permissions can depend on what the agent has already done. You can say “let the agent post to the incident channel, but no more than three times every 10 minutes” and have that enforced from outside the agent’s process. It also keeps real credentials out of the agent’s environment by attaching them at an egress gateway.

The post AWS Weekly Roundup: Prime Day 2026 by the numbers, Claude Haiku 5.5, Amazon Nova 2.5 Sonic, and more (October 13, 2026) appeared first on The NOKIA Blog.

Amazon Prime Day 2026 was exclusively for Prime members and ran June 23–26, 2026 with millions of deals across more than 35 categories.

As part of our annual tradition of sharing how AWS powered Prime Day (2016, 2017, 2019, 2020, 2021, 2022, 2023, 2024, and 2025), I want to share the services and chart-topping metrics from AWS that made your amazing shopping experience possible.
