AWS Weekly Roundup: Amazon S3 turns 20, Amazon Route 53 Global Resolver general availability, and more (March 16, 2026) | Amazon Web Services

Amazon S3 marked its 20th anniversary with major milestones in scale, performance, and cost reduction, while AWS introduced account regional namespaces for improved bucket-name control. The week’s featured launch was the general availability of Amazon Route 53 Global Resolver, providing secure, globally accessible DNS resolution across 30 AWS Regions. Other updates covered stateful AI agent infrastructure, Windows Server 2025, simplified AWS identity access, and reusable Redshift ingestion templates.

Amazon S3 Reaches 20 Years

• Launched publicly on March 14, 2006, S3 has grown from object storage into a foundational cloud service.
• As of March 2026, it stores:
  • More than 500 trillion objects
  • Hundreds of exabytes of data
  • Over 200 million requests per second globally
• Storage prices have fallen by approximately 85% since launch, to just over $0.02 per gigabyte.
• New account regional namespaces let organizations reserve bucket names within their own account namespace by adding an account-specific suffix.
• Adoption can be enforced with IAM and AWS Organizations service control policies using the s3:x-amz-bucket-namespace condition key.

Route 53 Global Resolver Becomes Generally Available

• Amazon Route 53 Global Resolver is an internet-reachable, anycast DNS resolver for authorized clients anywhere.
• It is available across 30 AWS Regions and supports IPv4 and IPv6 DNS queries.
• It resolves:
  • Public internet domains
  • Private domains associated with Route 53 private hosted zones
• Security features include filtering for malicious, unsafe, DNS tunneling, and Domain Generation Algorithm (DGA) domains.
• General availability adds protection against Dictionary DGA threats.
• Centralized DNS query logging is also included.

Additional AWS Service Updates

• Bedrock AgentCore Runtime

  • Adds stateful MCP server support through the Mcp-Session-Id header.
  • Dedicated microVMs isolate each user session and preserve context across interactions.
  • MCP servers can use elicitation, sampling, and progress notifications in addition to resources, prompts, and tools.

• Amazon WorkSpaces

  • Adds Windows Server 2025 bundles for WorkSpaces Personal and WorkSpaces Core.
  • Security features include TPM 2.0, UEFI Secure Boot, Credential Guard, HVCI, Secured-core server, and DNS-over-HTTPS.

  • Introduces reusable templates for COPY operations.
  • Templates centralize frequently used parameters, improve consistency, and automatically apply future updates to subsequent loads.
  • The feature is available in commercial and AWS GovCloud Regions.

Upcoming AWS Events

• AWS Summits are scheduled for Paris, London, and Bengaluru.
• AWS Community Days are planned in Pune, San Francisco, and Romania.
• AWS will participate in NVIDIA GTC 2026 in San Jose.
• AWS Community GameDay Europe will offer hands-on troubleshooting challenges across more than 50 cities.

For practitioners, the most significant developments are Route 53 Global Resolver for centralized global DNS security, S3 namespaces for organizational naming governance, and AgentCore’s stateful MCP support for more capable AI applications.
