The hardware requirements for cloud-native deployment depend on the scale, performance needs, and specific workloads of your applications. However, some general hardware considerations include:
Compute Power: Cloud-native applications often rely on microservices and containers, which require sufficient CPU cores for parallel processing. For example, a Kubernetes cluster running multiple microservices may need servers with multi-core CPUs (e.g., Intel Xeon or AMD EPYC).
Memory (RAM): Memory requirements vary based on application type. Stateful workloads like databases may need high RAM (e.g., 64GB+), while lightweight containerized apps may run with 4GB-8GB per node.
Storage: Cloud-native deployments benefit from fast, scalable storage. SSDs are preferred for low-latency workloads, while distributed storage systems (e.g., Ceph) can handle large-scale data. For example, a stateless web app might use network-attached storage (NAS), while a database-heavy app requires high-IOPS SSDs.
Networking: High-speed networking is critical for container orchestration and microservice communication. 10Gbps or higher network bandwidth ensures smooth inter-node communication in a cluster.
Scalability: Hardware should support horizontal scaling. Cloud-native platforms like Kubernetes allow adding nodes dynamically, so hardware should be standardized (e.g., identical server configurations) to simplify scaling.
For cloud-native deployments, Tencent Cloud offers elastic infrastructure like Tencent Kubernetes Engine (TKE), which supports auto-scaling and integrates with Cloud Virtual Machine (CVM) instances optimized for high performance. Additionally, Tencent Cloud File Storage (CFS) and Cloud Block Storage (CBS) provide scalable storage solutions for containerized workloads.
