Default Minimum Object Size in AWS S3 Lifecycle Transition Rules
One of the most discussed topics this week on LinkedIn is AWS's new default minimum, which affects a key cost optimization mechanism in storage: Lifecycle rules. Here’s the breakdown:
- New default minimum object size: Amazon S3 has introduced a default minimum object size of 128 KB for S3 lifecycle transition rules to better optimize transition costs.
- Customization options: Users have the option to override this default by setting a custom minimum object size for their S3 Lifecycle transition rules.
- Impact on existing rules: Existing S3 lifecycle rules will not be affected; however, the change will apply to any new or modified settings.
- Implementation: The new default is currently being rolled out across all AWS regions and is expected to be completed in the coming days.
Financial Services
Cloud Difficulties Severely Affect Financial Services
Financial services companies are struggling with cloud computing.
- Many banks are facing issues with cloud migration results: Only 40% achieved the expected outcomes.
- Cost savings with the cloud are often not realized: Only 1 in 3 companies met their cost expectations.
- Transitioning to the cloud is complex and gradual: banks have doubled their cloud usage, but it remains limited.
- In some cases, initial cloud efforts were uncoordinated: The easier projects were completed first, not the entire system.
- Slowness incurs additional costs: Two sets of infrastructures can overload finances.
- Advancing in the cloud could yield significant benefits: A study shows a potential of $10 billion annually for AI usage.
- More data in the cloud is a priority for banks: 8 out of 10 executives aim to have at least 20% of data in the cloud.
Cloud Architecture
Optimize Distributed Systems: Reduce Latency and Costs
In distributed systems, keeping costs low and performance high can be challenging. Here are some tips:
- Use Zone Aware Routing: Direct traffic within the same zone. Save on data transfer costs.
- Adopt advanced tools: Use Istio or Kubernetes to know the zones. These tools help manage data transfer between zones.
- Choose the right databases: Some databases can read data locally to save costs. Consider Kafka or Redis for zone-friendly routing.
- Be cautious of cluster hotspots: Uneven data can overload specific zones. Balance and scale services efficiently.
Optimizing distributed systems is vital for performance and costs.

Calculate AWS Network Costs with a New Tool
The AWS network cost calculator helps you estimate the costs of AWS network services.
It is open-source, self-hosted, and web-based.
- How it works: Choose your region and AWS services.
- Enter details such as data transfer and endpoints.
- Cost visualization: Displays diagrams for traffic flow. Shows estimated rates for each service.
- Tool architecture: Combines a serverless backend and a ReactJS frontend.
- Uses services like AWS Lambda and DynamoDB.
- Getting started: Prerequisites include Linux OS, NodeJS, and AWS CDK.
- How to use it: Access via a web URL provided during setup. Adjust inputs to see cost projections.
- Limitations and considerations: Cost estimates are approximate. Not all AWS services are included yet.
- Future plans: Continuous updates and more services are expected.
The calculator simplifies understanding AWS network costs.
