Strategies for Reducing Cloud Computing Expenses
Cloud architects can substantially reduce cloud expenses by right-sizing resources, leveraging reserved instances, implementing auto-scaling, utilizing spot instances, cleaning up unused resources, and optimizing data transfer costs. These steps, combined with continuous monitoring and optimization, can lead to significant cost reductions.
Steps for Cloud Architects to Dramatically Reduce Overall Spending on Cloud Computing
To achieve substantial savings in cloud computing, cloud architects can adopt several strategies focusing on optimizing resources and utilizing cost-effective configurations. These steps can lead to significant reductions in cloud spending:
Right-Sizing Resources: Evaluate and adjust the size of your computing resources to match workload requirements accurately. Utilize cloud providers’ tools to monitor performance and identify underutilized resources for downsizing.
Reserved Instances and Savings Plans: Commit to reserved instances or savings plans for critical, stable workloads to capitalize on lower pricing compared to pay-as-you-go rates.
Auto-Scaling: Implement auto-scaling to automatically adjust resources based on demand. This ensures that you’re only paying for the resources you need at any given time.
Spot Instances: For flexible, non-critical workloads, consider using spot instances. They can offer significant cost savings but require a strategy to handle potential interruptions.
Clean Up Unused Resources: Regularly review and terminate unused or idle resources, such as unattached volumes and obsolete snapshots, which can accumulate unnecessary charges.
Optimize Data Transfer Costs: Understand and manage data transfer costs by keeping data transfer within the same region and using cloud provider’s content delivery networks (CDNs) to reduce costs associated with data egress.
Cloud Cost Savings (AWS / Azure)
Strategic cost-saving measures in AWS and Azure include utilizing services like Amazon S3 Intelligent-Tiering and Azure Blob Storage lifecycle management for storage optimization, Amazon Glacier, and Azure Blob Storage Archive tier for data archival, and employing cost-effective solutions for disaster recovery and geo-replication. By calculating projected savings and applying targeted strategies, cloud architects can achieve substantial reductions in cloud spending.
Quick Tips for Cost Savings in AWS and Azure
AWS:
Storage: Use Amazon S3 Intelligent-Tiering for data with unknown or changing access patterns. Projected savings: up to 40% for infrequently accessed data.
Data Archival: Leverage Amazon Glacier for long-term archival. Savings can reach up to 72% compared to using standard S3 storage over 12 months.
Disaster Recovery: Implement cross-region snapshot copying only for critical data, and consider AWS Backup for centralized backup management.
Geo-replication: Utilize AWS Global Accelerator to improve global application availability and performance while potentially reducing costs by intelligently routing traffic.
Azure:
Storage: Use Azure Blob Storage access tiers (hot, cool, and archive) based on how frequently data is accessed. Cool and archive tiers can offer savings of up to 50% and 80% respectively over the hot tier.
Data Archival: Azure Blob Storage Archive tier is highly cost-effective for data that can tolerate retrieval delays, offering substantial savings over the cool and hot tiers.
Disaster Recovery: Azure Site Recovery offers a flexible, cost-effective solution for disaster recovery. Optimize by regularly reviewing and adjusting the replication frequency and retention policies.
Geo-replication: Azure Front Door Service provides intelligent layer-7 routing, enabling cost savings through efficient traffic management and acceleration.
Calculating Projected Savings
To calculate projected savings over a 12-month period, follow these steps:
Baseline Current Spend: Determine your current monthly spending on the specific service (e.g., storage, data transfer).
Apply Reduction Percentage: Based on the tip’s projected savings percentage, calculate the reduced monthly cost.
Calculate Annual Savings: Multiply the monthly savings by 12 to project annual savings.
Projected Savings=(Current Monthly Spend−(Current Monthly Spend×Reduction Percentage))×12
For instance, if your current monthly spend on S3 storage is $1,000 and you apply S3 Intelligent-Tiering, projecting a 40% reduction:
Projected Savings=($1,000−($1,000×0.4))×12=$7,200 annually
By meticulously applying these strategies and continuously monitoring their effectiveness, cloud architects can significantly reduce their cloud computing expenses while still meeting their organizations’ operational needs and performance standards.
Example: Azure Storage with 30k IOPS vs Samsung NVMe 2TB SSD with 1.5Million IOPS
Comparing the costs and performance between Azure Managed Disks and on-premises NVMe SSD storage offers a compelling example of how cloud architects can identify significant cost savings without compromising on performance. In this instance, an Azure Managed Disk (P40), offering "telco-grade" availability (or five-nines), can burst up to 30,000 IOPS, with pricing that includes on-demand bursting transaction charges at $0.005 per 10,000 IOs, in addition to a monthly enablement fee of $24.
Note from the author: I acknowledge that this example is a grossly oversimplified scenario which fails to account for numerous nuances / highly divergent use cases; but it still serves as an example of vast delta between the TCO of data in the cloud vs data on-prem.
A P40 2TiB drive's monthly fees for normal use would be $235.52 + $223.75 + $13.14 + $24 = $496.41 (per disk) + Egress retrieval fees (can be exponentially higher than standard Azure Blob Hot Storage retrieval rates)
Therefore, the total monthly cost for a P40 2TiB drive, under normal usage, comes to approximately $496.41 per disk.
In contrast, purchasing a Samsung 990 PRO 2TB SSD NVMe drive, which supports up to 1.5 million IOPS for sequential reads, costs only $179 at retail. This NVMe drive transfers data up to 25 times faster than traditional SATA drives, presenting an attractive option for high-performance needs at a fraction of the cost.
Azure Managed Disk Annual Costs: $496.41 * 12 months = $5,956.92
Samsung 990 PRO 2TB SSD NVMe = $179.00
Annual Savings: $5,777.92
This comparison illustrates how cloud architects have the potential to approach spending in vastly different ways. Some may spend liberally, akin to the unchecked budgets sometimes seen in governmental spending, while the most effective architects scrutinize every expense as if it were coming out of their own pocket. This mindset is critical for architects aiming to optimize cloud architectures for cost efficiency without sacrificing performance.
Such decisions hinge on a detailed understanding of workload requirements, performance metrics, and cost implications, emphasizing the need for thorough analysis and strategic planning in enterprise IT architecture.
