Automatic Instance Scaling: AWS EC2 vs Azure Virtual Machines vs Google Compute Engine

Source Link: Getting Started with Auto Scaling 

Automatic instance scaling is a crucial feature for cloud users aiming to optimize performance while managing costs efficiently. All three cloud providers—AWS EC2, Azure Virtual Machines, and Google Compute Engine (GCE)—offer robust automatic scaling capabilities. However, each platform approaches it in slightly different ways, catering to various workload needs and business requirements.

VM Scaling Services Comparison
Provider VM Scaling Service Organizational Unit Support for Guest VM Metrics Predictive Scaling Scheduled Scaling
AWS EC2 Auto Scaling Auto Scaling Groups (ASG) Yes - requires CloudWatch agent Yes Yes
AWS Auto Scaling
Azure Virtual Machine Scale Sets Virtual Machine Scale Sets (VMSS) Yes - requires Azure diagnostics extension No Yes
GCP Autoscaling Managed Instance Group (MIG) Yes - requires the Cloud Monitoring agent Yes Preview Feature

AWS EC2: Auto Scaling Groups and Load Balancing Capabilities

AWS EC2 provides automatic scaling through Auto Scaling Groups (ASG), which allow users to automatically adjust the number of instances based on demand. This is particularly useful for businesses experiencing fluctuating traffic patterns, as it ensures that resources are efficiently allocated without the need for manual intervention.

  • Auto Scaling Groups (ASG): ASGs allow users to define a minimum, maximum, and desired number of EC2 instances. AWS will automatically scale up or down based on predefined metrics like CPU utilization or memory usage. This flexibility allows businesses to optimize their resources according to real-time demand.
  • Load Balancing: AWS integrates Elastic Load Balancer (ELB) with Auto Scaling, enabling the distribution of incoming traffic across multiple instances. This ensures high availability and fault tolerance for applications, even during high traffic periods.

Example: A retail business using AWS EC2 can configure Auto Scaling for its application servers during peak shopping seasons like Black Friday. If traffic spikes due to increased demand, the Auto Scaling feature will add more instances automatically, and when the traffic returns to normal levels, it will scale down, reducing costs.

Azure Virtual Machines: Virtual Machine Scale Sets for Easy Scaling

Azure Virtual Machines takes a slightly different approach with Virtual Machine Scale Sets (VMSS). This service allows for the management and scaling of a group of identical VMs, making it easy to deploy, manage, and automatically scale applications. VMSS is integrated with Azure Load Balancer for distributing traffic across multiple VM instances, ensuring that your application can handle varying workloads efficiently.

  • Automatic Scaling with VMSS: Azure’s VMSS supports automatic scaling based on metrics such as CPU usage, memory usage, or custom metrics. You can set up scaling policies to automatically increase or decrease the number of VMs in response to changes in application demand, ensuring consistent performance and minimizing costs.
  • Integration with Azure Load Balancer: Like AWS, Azure provides built-in integration with the Azure Load Balancer, which ensures that incoming traffic is distributed evenly across the scaled VMs.

Example: For a financial services company utilizing Azure Virtual Machines, VMSS can automatically scale the infrastructure during busy periods like end-of-quarter financial closings. With Azure’s load balancing, the system can ensure that the service remains responsive and reliable, even under heavy traffic.

Google Compute Engine: Managed Instance Groups with Dynamic Scaling

Google Compute Engine (GCE) leverages Managed Instance Groups (MIGs) for automatic scaling. MIGs allow users to create a group of instances with identical configurations, and they are designed to scale dynamically based on demand. This makes GCE an excellent option for applications with unpredictable or highly variable workloads.

  • Dynamic Scaling: GCE provides dynamic scaling where instances in a MIG are added or removed automatically based on utilization. This means that as your application experiences higher demand, Google Cloud will spin up more instances, and when demand decreases, it will scale back down to save costs.
  • Integration with Google Cloud Load Balancing: GCE’s scaling integrates seamlessly with Google Cloud Load Balancing, ensuring that traffic is distributed efficiently across your instances, and providing global scalability with minimal latency.

Example: A startup running a video streaming service on Google Compute Engine can configure MIGs to automatically scale during periods of high demand (such as when a popular show is released) and scale back down during off-peak hours, minimizing costs and ensuring performance.

Sedai can be incredibly helpful when managing cloud resources and optimizing automatic instance scaling across AWS EC2, Azure Virtual Machines, and Google Compute Engine (GCE).

Temporary Instance Pricing and Usage

Source Link: Instance pricing calculation 

When it comes to temporary cloud instances, all three major cloud providers—AWS, Azure, and Google Cloud—offer flexible pricing models designed to help businesses optimize costs for non-mission-critical workloads. 

These instances are typically designed to be interruptible, meaning they can be terminated by the provider with little notice, making them an ideal choice for tasks that can handle sudden interruptions, such as batch processing, web servers, or temporary data analysis tasks.

1. AWS EC2 Spot Instances

AWS EC2 Spot Instances are a great way to save on computing costs by utilizing excess capacity available in AWS's data centers. The pricing is market-driven and can offer discounts of up to 90% compared to the standard on-demand pricing. Spot Instances are particularly beneficial for tasks that are flexible and can tolerate interruptions, such as data processing, CI/CD workloads, and running background jobs. However, the biggest challenge with Spot Instances is that they can be terminated by AWS with just a 2-minute notice if the capacity is needed by other users.

2. Azure Low-Priority VMs

Azure offers Low-Priority VMs, which are similar to AWS Spot Instances in that they are priced lower but are subject to being preempted by Azure at any time. These instances are great for workloads that are not time-sensitive and can be interrupted without significant impact. Azure's Low-Priority VMs offer up to 80% savings compared to regular on-demand VMs, making them an attractive option for running large compute-intensive tasks like big data processing, rendering, or testing.

3. Google Preemptible VMs

Google Cloud's Preemptible VMs offer an affordable and flexible solution for temporary workloads. Like AWS Spot Instances and Azure Low-Priority VMs, Preemptible VMs are priced at a significant discount (up to 80%) compared to regular on-demand pricing. 

These VMs can be preempted (terminated) with 30 seconds of notice, and they are ideal for stateless workloads such as batch jobs, video rendering, or scientific computations. Preemptible VMs in Google Cloud are especially useful when there is a need for cost-effective compute power without the expectation of long uptime.

AWS C5a.4xlarge 16 32 GB 128 GB Standard 3 years $1,002
Azure F16s v2 16 32 GB 128 GB Standard 3 years $905
Google Cloud c2-standard-16 16 64 GB 128 GB Standard 3 years $1,243

As mentioned earlier, various factors like data transfer, licensing, and software can affect the total cost, and these tables present the base cost for these two example scenarios only.

Here’s What These Actually Cost (Provide a Scenario)

Let’s consider a common use case where we need to run a medium-sized application that requires a 5 vCPU and 10 GB of memory. This could be a web server, database, or any workload that needs a reasonable balance between compute power and memory. To understand the actual cost of such a setup, we will compare the prices for each of the major cloud providers—AWS vs Azure vs Google Cloud—across their on-demand, spot, and reserved instance options.

Below is a detailed table showing the best instance type for each cloud provider, with similar specifications and the cost across different billing models (on-demand, spot, and reserved).

Scenario: 5 vCPU, 10 GB Memory - Instance Comparison

Best Instance Type Price Comparison
Cloud Provider Best Instance Type Specs On-Demand Price Spot Price Reserved Price
AWS T3.xlarge 4 vCPU, 10 GB memory, 32 GB SSD $0.1664/hour $0.0499/hour $0.099/hour
Azure D4s v3 5 vCPU, 10 GB memory, 32 GB SSD $0.192/hour $0.053/hour $0.095/hour
Google Cloud N2-standard-4 5 vCPU, 10 GB memory, 32 GB SSD $0.1292/hour $0.0387/hour $0.078/hour

This scenario shows a typical application requiring 5 vCPU and 10 GB of memory. As you can see, the pricing for each cloud provider varies significantly, especially when utilizing spot instances for cost optimization. AWS offers a significant discount through spot pricing, but there are trade-offs in terms of instance termination with no prior notice.

Cost Optimization Approach

Cloud providers offer several cost optimization features, but they are often not enough for businesses that need to optimize costs at scale, especially when operating thousands of vCPUs or large workloads. While cloud providers offer tools like visibility into costs, auto-scaling, and right-sizing recommendations, the need for intelligent, autonomous cloud optimization at scale is paramount for achieving long-term savings.

Below is a comparison of the optimization features available across AWS vs Azure vs  Google Cloud, highlighting their capabilities in cost visibility, right-sizing, autoscaling, and autonomous operations.

Cloud Provider Comparison
Cloud Provider Cost Visibility Right-Sizing Recommendations Autoscaling Autonomous Operations
AWS Yes, with CloudWatch Yes, via Compute Optimizer Yes, via EC2 Auto Scaling No autonomous instance adjustment
Azure Yes, with Cost Management + Billing Yes, via Azure Advisor Yes, via Virtual Machine Scale Sets No autonomous instance adjustment
Google Cloud Yes, with Cloud Billing Yes, via Recommender Yes, via Managed Instance Groups No autonomous instance adjustment

While all three cloud providers offer basic tools for cost visibility and some level of autoscaling, there are significant gaps when it comes to intelligent, autonomous cloud optimization.

Automatic Instance Scaling: AWS EC2 vs Azure Virtual Machines vs Google Compute Engine

Source Link: Getting Started with Auto Scaling 

Automatic instance scaling is a crucial feature for cloud users aiming to optimize performance while managing costs efficiently. All three cloud providers—AWS EC2, Azure Virtual Machines, and Google Compute Engine (GCE)—offer robust automatic scaling capabilities. However, each platform approaches it in slightly different ways, catering to various workload needs and business requirements.

VM Scaling Services Comparison
Provider VM Scaling Service Organizational Unit Support for Guest VM Metrics Predictive Scaling Scheduled Scaling
AWS EC2 Auto Scaling Auto Scaling Groups (ASG) Yes - requires CloudWatch agent Yes Yes
AWS Auto Scaling
Azure Virtual Machine Scale Sets Virtual Machine Scale Sets (VMSS) Yes - requires Azure diagnostics extension No Yes
GCP Autoscaling Managed Instance Group (MIG) Yes - requires the Cloud Monitoring agent Yes Preview Feature

AWS EC2: Auto Scaling Groups and Load Balancing Capabilities

AWS EC2 provides automatic scaling through Auto Scaling Groups (ASG), which allow users to automatically adjust the number of instances based on demand. This is particularly useful for businesses experiencing fluctuating traffic patterns, as it ensures that resources are efficiently allocated without the need for manual intervention.

  • Auto Scaling Groups (ASG): ASGs allow users to define a minimum, maximum, and desired number of EC2 instances. AWS will automatically scale up or down based on predefined metrics like CPU utilization or memory usage. This flexibility allows businesses to optimize their resources according to real-time demand.
  • Load Balancing: AWS integrates Elastic Load Balancer (ELB) with Auto Scaling, enabling the distribution of incoming traffic across multiple instances. This ensures high availability and fault tolerance for applications, even during high traffic periods.

Example: A retail business using AWS EC2 can configure Auto Scaling for its application servers during peak shopping seasons like Black Friday. If traffic spikes due to increased demand, the Auto Scaling feature will add more instances automatically, and when the traffic returns to normal levels, it will scale down, reducing costs.

Azure Virtual Machines: Virtual Machine Scale Sets for Easy Scaling

Azure Virtual Machines takes a slightly different approach with Virtual Machine Scale Sets (VMSS). This service allows for the management and scaling of a group of identical VMs, making it easy to deploy, manage, and automatically scale applications. VMSS is integrated with Azure Load Balancer for distributing traffic across multiple VM instances, ensuring that your application can handle varying workloads efficiently.

  • Automatic Scaling with VMSS: Azure’s VMSS supports automatic scaling based on metrics such as CPU usage, memory usage, or custom metrics. You can set up scaling policies to automatically increase or decrease the number of VMs in response to changes in application demand, ensuring consistent performance and minimizing costs.
  • Integration with Azure Load Balancer: Like AWS, Azure provides built-in integration with the Azure Load Balancer, which ensures that incoming traffic is distributed evenly across the scaled VMs.

Example: For a financial services company utilizing Azure Virtual Machines, VMSS can automatically scale the infrastructure during busy periods like end-of-quarter financial closings. With Azure’s load balancing, the system can ensure that the service remains responsive and reliable, even under heavy traffic.

Google Compute Engine: Managed Instance Groups with Dynamic Scaling

Google Compute Engine (GCE) leverages Managed Instance Groups (MIGs) for automatic scaling. MIGs allow users to create a group of instances with identical configurations, and they are designed to scale dynamically based on demand. This makes GCE an excellent option for applications with unpredictable or highly variable workloads.

  • Dynamic Scaling: GCE provides dynamic scaling where instances in a MIG are added or removed automatically based on utilization. This means that as your application experiences higher demand, Google Cloud will spin up more instances, and when demand decreases, it will scale back down to save costs.
  • Integration with Google Cloud Load Balancing: GCE’s scaling integrates seamlessly with Google Cloud Load Balancing, ensuring that traffic is distributed efficiently across your instances, and providing global scalability with minimal latency.

Example: A startup running a video streaming service on Google Compute Engine can configure MIGs to automatically scale during periods of high demand (such as when a popular show is released) and scale back down during off-peak hours, minimizing costs and ensuring performance.

Temporary Instance Pricing and Usage

Source Link: Instance pricing calculation 

When it comes to temporary cloud instances, all three major cloud providers—AWS, Azure, and Google Cloud—offer flexible pricing models designed to help businesses optimize costs for non-mission-critical workloads. 

These instances are typically designed to be interruptible, meaning they can be terminated by the provider with little notice, making them an ideal choice for tasks that can handle sudden interruptions, such as batch processing, web servers, or temporary data analysis tasks.

1. AWS EC2 Spot Instances

AWS EC2 Spot Instances are a great way to save on computing costs by utilizing excess capacity available in AWS's data centers. The pricing is market-driven and can offer discounts of up to 90% compared to the standard on-demand pricing. Spot Instances are particularly beneficial for tasks that are flexible and can tolerate interruptions, such as data processing, CI/CD workloads, and running background jobs. However, the biggest challenge with Spot Instances is that they can be terminated by AWS with just a 2-minute notice if the capacity is needed by other users.

2. Azure Low-Priority VMs

Azure offers Low-Priority VMs, which are similar to AWS Spot Instances in that they are priced lower but are subject to being preempted by Azure at any time. These instances are great for workloads that are not time-sensitive and can be interrupted without significant impact. Azure's Low-Priority VMs offer up to 80% savings compared to regular on-demand VMs, making them an attractive option for running large compute-intensive tasks like big data processing, rendering, or testing.

3. Google Preemptible VMs

Google Cloud's Preemptible VMs offer an affordable and flexible solution for temporary workloads. Like AWS Spot Instances and Azure Low-Priority VMs, Preemptible VMs are priced at a significant discount (up to 80%) compared to regular on-demand pricing. 

These VMs can be preempted (terminated) with 30 seconds of notice, and they are ideal for stateless workloads such as batch jobs, video rendering, or scientific computations. Preemptible VMs in Google Cloud are especially useful when there is a need for cost-effective compute power without the expectation of long uptime.

High-Spec VM Cost Comparison
Provider VM Type vCPUs Memory Attached Storage Reservation Term Total Monthly Cost
AWS C5a.4xlarge 16 32 GB 128 GB Standard 3 years $1,002
Azure F16s v2 16 32 GB 128 GB Standard 3 years $905
Google Cloud c2-standard-16 16 64 GB 128 GB Standard 3 years $1,243

As mentioned earlier, various factors like data transfer, licensing, and software can affect the total cost, and these tables present the base cost for these two example scenarios only.

Here’s What These Actually Cost (Provide a Scenario)

Let’s consider a common use case where we need to run a medium-sized application that requires a 5 vCPU and 10 GB of memory. This could be a web server, database, or any workload that needs a reasonable balance between compute power and memory. To understand the actual cost of such a setup, we will compare the prices for each of the major cloud providers—AWS vs Azure vs Google Cloud—across their on-demand, spot, and reserved instance options.

Below is a detailed table showing the best instance type for each cloud provider, with similar specifications and the cost across different billing models (on-demand, spot, and reserved).

Scenario: 5 vCPU, 10 GB Memory - Instance Comparison

Best Instance Type Price Comparison
Cloud Provider Best Instance Type Specs On-Demand Price Spot Price Reserved Price
AWS T3.xlarge 4 vCPU, 10 GB memory, 32 GB SSD $0.1664/hour $0.0499/hour $0.099/hour
Azure D4s v3 5 vCPU, 10 GB memory, 32 GB SSD $0.192/hour $0.053/hour $0.095/hour
Google Cloud N2-standard-4 5 vCPU, 10 GB memory, 32 GB SSD $0.1292/hour $0.0387/hour $0.078/hour

This scenario shows a typical application requiring 5 vCPU and 10 GB of memory. As you can see, the pricing for each cloud provider varies significantly, especially when utilizing spot instances for cost optimization. AWS offers a significant discount through spot pricing, but there are trade-offs in terms of instance termination with no prior notice.

Cost Optimization Approach

Cloud providers offer several cost optimization features, but they are often not enough for businesses that need to optimize costs at scale, especially when operating thousands of vCPUs or large workloads. While cloud providers offer tools like visibility into costs, auto-scaling, and right-sizing recommendations, the need for intelligent, autonomous cloud optimization at scale is paramount for achieving long-term savings.

Below is a comparison of the optimization features available across AWS vs Azure vs  Google Cloud, highlighting their capabilities in cost visibility, right-sizing, autoscaling, and autonomous operations.

Cloud Provider Comparison
Cloud Provider Cost Visibility Right-Sizing Recommendations Autoscaling Autonomous Operations
AWS Yes, with CloudWatch Yes, via Compute Optimizer Yes, via EC2 Auto Scaling No autonomous instance adjustment
Azure Yes, with Cost Management + Billing Yes, via Azure Advisor Yes, via Virtual Machine Scale Sets No autonomous instance adjustment
Google Cloud Yes, with Cloud Billing Yes, via Recommender Yes, via Managed Instance Groups No autonomous instance adjustment

While all three cloud providers offer basic tools for cost visibility and some level of autoscaling, there are significant gaps when it comes to intelligent, autonomous cloud optimization. For large-scale operations, such as those running thousands of vCPUs or handling large workloads, manually adjusting autoscaling configurations or selecting the appropriate instance type can become cumbersome and inefficient.
