What is a Hybrid Cloud?

Demystifying the Hybrid Cloud: A Personal Journey

This article shares a firsthand account of building and deploying a hybrid cloud during the 2021 pandemic. It offers a unique perspective on the cost-effectiveness and practicality of hybrid cloud solutions in real-world scenarios.

The Genesis of a Hybrid Cloud

The author begins by discussing the acquisition of surplus compute resources, making a case for building a hybrid cloud with high-performance, cost-effective hardware. This section highlights how an HP Z820, with impressive specifications, became the cornerstone of the author’s hybrid cloud.

Hybrid Cloud: The In-Home Lab Meets the Public Cloud

The concept of a hybrid cloud is introduced as a combination of an in-home lab connected to a public cloud. The article explores the financial and technical aspects of setting up such a system, contrasting it with the ongoing costs of fully cloud-based solutions.

Cost Analysis: Public Cloud vs. Hybrid Cloud

A detailed cost analysis compares the expenses of running services entirely in the public cloud versus a hybrid cloud setup. The author provides a breakdown of costs for AWS services and compares them with the one-time investment in an in-house lab, illustrating the long-term savings of a hybrid cloud model.

Overcoming Challenges and Leveraging Cloud Services

The article addresses potential challenges, such as power outages, and the benefits of having a minimal footprint in the public cloud for failover scenarios. It also discusses the integration of cloud services like Google Firebase for cost-effective database and web hosting solutions.

Innovations in Hybrid Cloud Deployment

The narrative includes innovative approaches to deploying demos and services using Docker in a hybrid environment. It showcases an automatic failover mechanism, where an AWS VM steps in to deploy services if the in-house system fails.

Machine Learning and Cost Considerations

The author touches on the use of machine learning for efficient resource allocation and the cost implications of using dedicated GPUs in the public cloud. A comparison is drawn between AWS GPU instances and owning a dedicated GPU for in-house processing.

Conclusion: A Viable Solution for Dynamic Needs

Concluding with a reflection on the versatility and economic sense of the hybrid cloud, the author advocates for this model as a feasible solution for businesses with dynamic computing needs and budget constraints.
