Cloud Bursting vs. Cloud Optimization: What Is the Difference? (Gilad David Maayan)

Updated: Jun 20, 2023


What Is Cloud Bursting?

Cloud bursting is a technique for running an application in a private cloud or data center and "bursting" to a public cloud when additional computing resources are required. This allows an organization to leverage the scalability of the public cloud while still maintaining control and security of sensitive data in their private cloud or data center. Cloud bursting is often used to handle sudden, unexpected spikes in traffic or demand for resources.

How Does Cloud Bursting Work?

Cloud bursting works by having an application run in a private cloud or data center, and then automatically or manually switching to a public cloud when additional computing resources are required. It requires setting up two different environments capable of running the application.


Automated cloud bursting:


● An application is configured to automatically scale up or down based on predefined thresholds, such as CPU usage, memory usage, or network traffic.

● The application is continuously monitored, and when a threshold is crossed, additional resources are automatically provisioned in the public cloud.

● Once the threshold is no longer crossed, the additional resources are automatically de-provisioned.


Manual cloud bursting:


● An application is running on a private cloud or data center and when additional resources are needed, a manual action is taken to spin up additional resources in the public cloud.

● This manual action can be initiated by an administrator or through a self-service portal by the user.

● Once the resources are no longer needed, manual action is taken to de-provision the resources in the public cloud.

What Is Cloud Optimization?

Cloud optimization refers to the process of fine-tuning and adjusting the configuration of cloud resources to enhance the performance, efficiency, and cost-effectiveness of a cloud-based application or service. Cloud optimization can involve a variety of strategies and techniques, such as:


Right-sizing resources: Ensuring that the resources being used by an application or service are the appropriate size for the workload.

Automated scaling: Automatically scaling resources up or down based on predefined thresholds, such as CPU usage, memory usage, or network traffic.

Load balancing: Distributing workloads across multiple resources to ensure that no single resource becomes overburdened.

Cloud cost management: Identifying and eliminating unnecessary or underutilized resources in order to reduce costs.

Security hardening: Ensuring that security measures such as firewalls, intrusion detection, and encryption are in place and properly configured.

Monitoring and logging: Collecting and analyzing performance data to identify potential issues and optimize performance.

How Does Cloud Optimization Work?

IT practitioners often discuss cloud optimization as if it is one thing, but there are several ways to optimize cloud environments and cloud-based applications or services. Typically, an organization’s cloud optimization strategy will include multiple aspects, including:


Cost optimization: Cloud cost optimization is the process of identifying and implementing strategies to reduce costs associated with using cloud computing resources. It can be achieved through different techniques such as right-sizing resources, auto-scaling, scheduling, resource allocation optimization, cloud service provider optimization, and cost monitoring.

Performance optimization: In the cloud, performance optimization means making sure applications and services run as quickly as possible. It can be achieved through different techniques such as load balancing, auto-scaling, caching, and Content Delivery Network (CDN).

Reliability optimization: Cloud reliability optimization is the process of improving the reliability of cloud-based applications and services. It can be achieved through different techniques such as Redundancy, Backup and recovery, High availability, and Disaster recovery. This ensures that cloud-based services and applications are available, even in the case of failures or outages, which can be caused by various factors like natural disaster, cyber-attack, and system failures.

Sustainability optimization: Cloud sustainability optimization is the process of improving the environmental and energy efficiency of cloud-based applications and services. This can be achieved through a variety of techniques such as energy-efficient hardware, green data centers, renewable energy, and virtualization. This ensures that the cloud usage is not only cost-effective, but also environmentally responsible by minimizing the carbon footprint and energy consumption.

Cloud Bursting vs. Cloud Optimization: What Are the Differences?

Cloud bursting and cloud optimization are two different strategies for utilizing cloud computing resources. Both strategies are aimed at improving the performance and cost-effectiveness of an organization's use of cloud computing resources. However, they approach this goal in different ways.


Cloud bursting is a technique where an organization uses cloud computing resources to handle a sudden increase in demand for their applications or services. This allows the organization to temporarily "burst" into the cloud to handle the increased load, rather than having to maintain extra capacity on their own servers all the time. For example, if an e-commerce website experiences a spike in traffic during a sale, cloud bursting can automatically provision additional resources in the cloud to handle the increased load, and then release those resources when the traffic subsides. This way, the organization only pays for the additional resources they need, when they need them, rather than having to maintain extra capacity all the time.


Cloud optimization, on the other hand, is a strategy for improving the performance and cost-effectiveness of an organization's use of cloud computing resources. This may involve techniques such as load balancing, autoscaling, and right-sizing of resources to ensure that the organization is using the right amount of resources at the right time. For example, if an organization is using more resources than it needs, cloud optimization can automatically scale down those resources to reduce costs. Similarly, if an organization is using too few resources, cloud optimization can automatically scale up resources to ensure that performance is not impacted.


Cloud optimization is more of a continuous process, organizations can monitor their cloud resource usage and performance, and then make adjustments as needed to optimize their cloud resources. They can also implement policies and automation that can help to optimize their cloud resources in real-time. For example, you can configure your cloud resources to automatically scale up or down based on usage patterns, or you can set up alerts to notify you when resources are running low or high.

Conclusion

In conclusion, cloud bursting and optimization are two different techniques used to manage and optimize cloud-based applications and services. Both cloud bursting and cloud optimization are important for organizations that are using the cloud to ensure that their applications and services are performing at their best.


Cloud bursting helps organizations to handle unexpected spikes in traffic or demand for resources, while cloud optimization helps organizations to improve the performance, efficiency, and cost-effectiveness of their cloud-based applications and services. With the right approach and the right tools, organizations can effectively manage and optimize their cloud-based applications and services to meet their specific business needs.
