AWS Graviton instances
AWS Graviton instances are a family of Amazon EC2 instances powered by ARM-based processors. These instances offer competitive performance while being cost-effective. Graviton instances are particularly well-suited for disk-bound and CPU-bound workloads. Organizations looking to optimize costs without compromising performance should consider integrating Graviton instances into their infrastructure.
Features of AWS Graviton Instances
- Cost-Effective: Graviton instances are designed to provide excellent price-performance ratios. They cost up to 20% less than comparable x86-based Amazon EC2 instances1.
- ARM-Based Architecture: Graviton instances utilize ARM processors, which offer a different architecture than traditional x86 CPUs.
- Performance: While ARM processors were once associated with mobile devices, AWS Graviton instances deliver competitive performance. They are particularly well-suited for disk-bound and CPU-bound workloads2.
- Memory Optimized: Graviton instances come in various flavors, including memory-optimized options. These are ideal for applications that require substantial memory resources.
Classes of AWS Graviton Instances
- General Purpose Instances (M7g, M7gd):
- These instances strike a balance between compute, memory, and networking.
- Ideal for general-purpose workloads such as application servers, midsize data stores, microservices, and cluster computing.
- Powered by AWS Graviton3 processors.
2. Compute-Optimized Instances (T4g):
- Best suited for burstable general-purpose workloads.
- Great for large-scale microservices, small and medium databases, virtual desktops, and business-critical applications.
- Powered by AWS Graviton2
3. Memory-Optimized Instances (M6gd, C6gd, R6gd):
- These instances cater to memory-intensive applications.
- Offer local NVMe-based SSD storage options.
- C6gnand C7gn instances, with enhanced networking and support for Elastic Fabric Adapter (EFA), are also available.
4. Accelerated Computing Instances (X2gd, G5g, Im4gn, Is4gen, I4g):
- Designed for specialized workloads that require acceleration.
- Examples include machine learning, high-performance computing (HPC), and data analytics.
Comparison with x86 Instances
Cost Comparison
- Graviton vs. x86: Graviton instances are generally more cost-effective than traditional x86 processors. AWS provides better prices for Graviton instances, making them attractive for price-conscious customers. Graviton processors offer 15-25% better price-performance for disk-bound and CPU-bound workloads2.
- Spot Prices: Sometimes, ARM instances can even exceed x86 spot prices. However, in many cases, ARM instances cost significantly less than their x86 equivalents3.
Performance Comparison
- Computational Performance: AWS Graviton instances perform similarly to x86_64 instances. Considering their lower cost, they offer better cost-effectiveness4.
- Application Resilience: Customers often use mixed-CPU architectures (combining Graviton and x86 instances) to improve overall application resilience. Testing application performance in a controlled environment before production deployment is recommended5.
Implementation Steps
- Evaluate Workload Suitability: Assess whether your workload fits Graviton instances well. Consider factors like CPU requirements, memory needs, and I/O demands.
- Transition Guide: Follow AWS’ transition guide to port your application to Graviton. Validate your workload’s performance in a test environment.
- Cost Estimation: Use the AWS pricing calculator to estimate costs for running instances on different processors (x86 and Graviton). Compare costs and performance metrics.
- Integration with Amazon EKS: If you’re using Amazon Elastic Kubernetes Service (Amazon EKS), integrate Graviton-based EC2 instances into your existing environment. You can mix Graviton and x86 instances to optimize cost and resiliency5.
