A traditional 3-tier architecture-based private cloud
We can build a private cloud using traditional 3-tier systems with various software products included in order to build a partially integrated SDDC solution. We have gone through various traditional 3-tier integrated systems or converged infrastructures as well as 3-tier do-it-yourself (DIY) reference architectures. Figure 3 shows the basic approach to the rack design using a traditional 3-tier architecture:
- Networking: Spine and Leaf based on networking provided by industry leaders. Hardware-based load balancing and security was used when needed in lieu of software-based.
- Management cluster: A dedicated set of isolated servers forms a compute cluster, which is sized to host all dedicated management software for operating both the hardware and virtualization software infrastructure.
- Compute cluster: A dedicated set of servers reserved exclusively for hosting private cloud workloads. All servers were based on blade servers with necessary...
