Cloud bursting

What is cloud bursting?

Cloud bursting presents several challenges that organizations need to address for successful implementation: 

• Compatibility and integration: Ensuring that applications and workloads are compatible with both private and public cloud environments can be complex. Integration between different cloud platforms may require significant effort and specialized tools.
• Data Security and compliance: Transferring data between private and public clouds can expose sensitive information to security risks. Ensuring compliance with regulations and maintaining data privacy during these transfers is a critical challenge. 
• Latency and performance: Latency issues can arise when data and applications are split between private and public clouds, potentially impacting performance, especially for real-time applications. 
• Cost management: While cloud bursting can be cost-effective, managing and predicting costs associated with dynamic scaling in public clouds can be difficult. Unexpected spikes in resource usage can lead to higher-than-anticipated expenses. 
• Complexity in monitoring and management: Managing a hybrid environment with cloud bursting requires advanced monitoring tools and robust management practices. Keeping track of resource utilization, performance metrics, and system health across both private and public clouds can be challenging. 
• Network bandwidth: Sufficient network bandwidth is essential to support the transfer of data and workloads between private and public clouds. Insufficient bandwidth can lead to bottlenecks and degraded performance. 
• Licensing and compliance: Certain software licenses may not permit running in a cloud-bursting scenario or may require additional licenses, complicating deployment and increasing costs. 
• Disaster recovery: Ensuring consistent and reliable disaster recovery plans that encompass both private and public cloud environments adds another layer of complexity. 

Addressing these challenges requires careful planning, robust architecture, and the use of advanced tools and technologies to ensure seamless operation and security in a cloud bursting. 

Organizational needs for cloud bursting: 

• Software development: 

- Variable workloads: During software development, organizations often experience fluctuating demands for computing resources. Cloud bursting allows them to scale up resources when intensive tasks such as code compilation, testing, or deployment require additional capacity. 

- Resource optimization: Developers can benefit from on-demand access to additional computing power from the public cloud, ensuring efficient resource utilization without needing a permanently expanded on-premises infrastructure. 

• Marketing campaigns: 

- Bursts of traffic: Marketing campaigns, especially those involving online promotions or product launches, can lead to sudden spikes in website traffic. Cloud bursting enables organizations to expand their server capacity seamlessly to handle increased web traffic during these campaign peaks. 

- Cost-Efficient Scaling: Rather than maintaining excess capacity year-round, organizations can leverage the public cloud for burst scaling during specific marketing initiatives, optimizing costs while ensuring a responsive online presence. 

• Extensive data modeling and queries: 

- Compute-intensive tasks: Big data analytics often involves computationally intensive tasks like complex modeling and queries, machine learning, or simulations, video rendering or transcoding. Cloud bursting allows organizations to access additional computing resources on demand, ensuring the timely processing of large datasets without overwhelming local infrastructure. 

- Scalable processing power: Public cloud resources provide scalable processing power for big data workloads, allowing organizations to handle peak demands and derive insights from large datasets efficiently. 

• Seasonal businesses: 

- Fluctuating demand: Seasonal businesses, like retail during holidays or outdoor activities during specific weather conditions, experience fluctuating demand for IT resources. Cloud bursting is instrumental in dynamically scaling infrastructure to accommodate increased demand during peak seasons. 

- Cost savings: Rather than investing in and maintaining infrastructure for the highest seasonal demand, organizations can use cloud bursting to scale resources as needed, optimizing costs while ensuring a seamless customer experience.

• HPE GreenLake, a suite of cloud services from Hewlett Packard Enterprise, provides a flexible 'as-a-service' solution with a pay-per-use infrastructure model, making it ideal for implementing cloud bursting.
