Challenges of Modern Data Centers

Large data volumes and modern applications generate high-performance distributed storage needs. Traditional storage systems can fall short in terms of scalability, accessibility, and data continuity.

Distributed data structures and increasing access demands complicate management processes, while decentralized storage architectures can reduce operational efficiency. Backup, data protection, and multi-access management can make operational sustainability harder; hardware dependency and data access interruptions can create critical operational risks.

What Problems Does It Solve?

  • Scalability issues
  • Centralized storage bottlenecks
  • Data continuity problems
  • Hardware dependency

Core Principles

Distributed Architecture

High availability is achieved by distributing data across different servers.

High Availability

Uninterrupted access and service continuity are supported.

Flexibility

Capacity needs can be met through horizontal growth.

Automation

Data balance is preserved with self-healing mechanisms.

How Does Ceph Work?

Ceph writes data to different nodes in a distributed architecture to provide high availability, data integrity, and a scalable storage infrastructure.

Workflow

1. Data Writing

  • S3 requests arrive at RGW.
  • Bucket access is controlled.
  • Replication processes are managed.

2. Continuity

  • Zone structures run synchronously.
  • Data is transferred to different locations.
  • Access continuity is preserved.

3. Data Protection

  • Data replication is applied.
  • Erasure coding runs.
  • Data integrity is preserved.
  • Disaster scenarios are supported.

Continuous Improvement

The Ceph infrastructure is optimized according to usage needs; performance, data continuity, and storage operations are continuously enhanced.

Advantages

Ceph RGW

Provides an S3-compliant object storage infrastructure.

Horizontal Scaling

Cluster capacity can be expanded according to the increasing data volume.

Multisite Replication

Data can be automatically replicated to different geographical locations.

Self-Healing

Data integrity is automatically preserved in case of hardware failures.
