• AWS EC2 Instance Comparison: C4 vs C5

    Amazon recently introduced the next generation of their compute-optimized instances: EC2 C5 instances. Compute instances are well suited to compute-heavy workloads such as batch processing, distributed analytics, high-performance computing etc.

    If you are considering whether you should migrate your workload from the previous generation instance families to C5, then the next couple of sections should help with the decision.

    What’s new in C5?

    The C5 instances are powered by the Skylake processor from Intel. The Skylake processor has several improvements over the Haswell processor which is used in the C4 instance family.

  • How to create a blog on AWS using S3 in 3 easy steps

    Why should you care about where to host your blog?

    Have you ever had to face any of these issues with your site?

    • Reliability: Frequent downtime leading to bad user experience. There could be many reasons for this such as hardware failures, security issues or application errors.
