4 Things To Optimize in Your Cloud Environment
Here are some of the main aspects of cloud optimization.
Cost reduction is the most important factor in cloud optimization for most companies. A major issue with cloud computing is that you can easily overspend by allocating more resources to your workloads than you would on-premises.
The complex nature of cloud pricing models further exacerbates this problem. Cloud service providers often have pricing menus charging different rates for the same services in different regions or times.
The cloud provider’s cost monitoring tools can help solve this problem (i.e., Cost Optimization Monitor for AWS and Cost Alerts for Azure). You can use these tools to understand your spending better and alert you when you overspend.
However, cloud providers do not intervene to prevent users from spending too much on their platforms. They do not provide tools to work across hybrid and multi-cloud environments. As a result, cloud cost optimization strategies usually include multiple tools and methods, such as third-party services for multi-cloud architectures, rather than native, vendor-specific offerings.

Optimizing performance in the cloud means ensuring your services and applications operate quickly and smoothly.
Cloud performance, like cost, is a complex subject depending on many factors. One important aspect to consider is the cloud architecture’s design. For instance, a cloud architecture that requires frequent data transmission between different regions or separate clouds can suffer from poor performance due to network latency and bottlenecks.
The type of cloud service you choose may also affect performance. Virtual Machine (VM) resource allocation may be more constrained for certain workloads—serverless features may perform better than standard VMs.
Even if the code is not explicitly cloud-specific, its underlying efficiency can significantly impact cloud performance. You should regularly test the performance of all application code before deployment.
Failures of the hosting cloud can make a cloud-based workload unavailable. Sometimes, workloads become unreliable because of inherent problems. It is important to mitigate these risks to maximize the reliability of your cloud applications.
Providing redundancy is a solid strategy for ensuring reliability. It involves a company deploying multiple instances of a single workload across multiple regions within a cloud or in separate clouds. However, this type of protection is often expensive, so it is important to balance the redundancy strategy with cost optimization objectives for the best overall results.
Third-party solutions that ensure enterprise-level SLAs across multiple clouds can complement these strategies as well.

Operating in the cloud can make it difficult to accurately identify security vulnerabilities and implement the appropriate security measures to mitigate them. You can handle this challenge by achieving centralized visibility and leveraging tools that provide actionable security insights.
A tool with dedicated security measures can address the most common, severe threats you expect your cloud systems to face. Ensure the technology provides both preventive and reactive measures, such as:
- Pre-event awareness – involves assessing risks and implementing the appropriate safeguards before events occur. Notable pre-event safeguards include container visibility, VPNs, and virtual machine (VM) encryption.
- Post-event awareness – apply measures that assist in identifying and responding to security events effectively and quickly. Common post-even techniques include DevSecOps practices, security risk mitigation tools, and compliance automation.
Cloud Optimization Services and Tools
The major public cloud vendors, including Microsoft Azure, Google Cloud, and Amazon Web Services (AWS), have an overwhelming price range with thousands of possible combinations of services and technologies based on different pricing models. Even highly experienced IT professionals and businesses find navigating the sheer volume of offerings difficult.
Fortunately, cloud optimization service providers help organizations achieve their cloud optimization requirements and business objectives. Companies can use a cloud optimization service to identify areas for improvement in the cloud and reduce costs, increase efficiency, establish organizational optimization strategies, and manage cloud infrastructure to enable continuous optimization.
Cloud optimization services provide access to certified cloud experts who work with customers as an extension of their internal IT team. They conduct independent audits of the cloud environment and highlight key areas where the company can optimize costs.
These services can benefit your company in the following important ways.
Reduce Costs and Invest Smarter
Many organizations waste money on redundant and over-provisioned infrastructure, consuming a large portion of their overall cloud spending. Optimizing costs across a large organization can result in significant savings and money to put into better investments. By optimizing cloud infrastructure, companies can cut up to half of their overall cloud spend, creating opportunities to invest in more strategic needs such as innovation and growth.
Transparency and visibility are essential for cost management. Cloud optimization services provide accurate and meaningful reports on how each business unit uses resources, how much they spend, and where they can improve efficiency. Increased visibility allows organizations to tailor their cloud spending to their business needs.
In addition to controlling costs, cloud optimization services increase visibility across cloud environments. They allow business teams to strategize and scale their cloud services confidently.
To maintain optimal performance, cloud management partners should right-size the cloud environment. They check your usage and create a workload heatmap to find idle resources and identify when you can spin down resources. This approach helps you migrate any resource that can run on a smaller instance without impacting performance. It reduces waste and keeps the cloud running at optimal capacity.
Access Skills and Expertise
With more enterprises migrating to the cloud, the demand for technical expertise is also increasing. However, many companies lack in-house expertise, creating a cloud skills gap. Given the steep rise in demand and the competition over limited personnel, the skills gap has nearly doubled in recent years for most companies.
A cloud optimization service can help fill the skills gap by providing access to a team of experienced, certified cloud experts to complement the internal IT team, while also providing tools that are purpose-built for cloud optimization.
Cloud Optimization Best Practices
Right-Sizing Computing Services
Right-sizing is one of the best practices in cloud optimization that allows businesses to match their cloud services with the workload requirements effectively. This approach involves choosing the right type of instances or services and the appropriate size to fit the actual workload demand.
Right-sizing requires you to analyze workload patterns and utilization metrics continuously. By leveraging machine learning algorithms, businesses can effectively forecast their future needs based on historical data. This allows them to avoid overprovisioning and underprovisioning resources, resulting in better cost efficiency and improved performance.
Making Use of Spot Instances
Spot instances are a cost-effective way to utilize cloud resources, particularly for workloads that are not time-sensitive. Cloud providers such as AWS offer Spot instances, which are spare compute capacity available at a significantly lower cost than on-demand pricing.
However, spot instances can be interrupted by the cloud provider with little notice when the demand for these resources increases. Therefore, they are most effective for tasks that can be stopped and restarted without any critical impact, like batch jobs, data analysis, or development and test environments. With advanced automation, spot instances can be used even for critical workloads that cannot tolerate interruptions.
Investing in Reserved Instances
Reserved instances are another effective cloud optimization practice that can significantly reduce costs. These are commitments to use specific services for a longer period, usually one or three years, and in return, the provider offers substantial discounts compared to on-demand pricing.
Reserved instances are best suited for predictable and steady workloads. While this approach involves a long-term commitment, it can provide cost savings of up to 75% compared to on-demand instances.
Identifying Unused Resources and Removing Them
As part of cloud optimization, it’s crucial to regularly review and remove unused or underused resources. These can include idle instances, unattached storage volumes, or outdated snapshots. These resources, although idle, still contribute to costs.
The use of monitoring and management tools can provide a comprehensive view of the cloud environment and enable the identification of such resources. Regular audits and clean-ups not only reduce costs but also improve the management and security of the cloud environment.
Merging Idle Resources
Merging idle resources is another effective cloud optimization strategy. During off-peak hours, several instances might be under-utilized. By merging these workloads, you can ensure better utilization of your resources while reducing the overall cost.
Auto-scaling and load balancing are two key technologies for this purpose. Auto-scaling adjusts the number of active instances based on the demand, and load balancing distributes network traffic across multiple servers to ensure no single server bears too much demand.
