Understanding Reserved Instances and Savings Plans in AWS

What are Reserved Instances and Savings Plans?
Reserved Instances and Savings Plans are ways to save money on Amazon Web Services (AWS) by committing to use certain resources over a period of time. They help businesses spend less on cloud services while still getting the resources they need.

What are Reserved Instances?

Reserved Instances (RIs) let you reserve a specific amount of computing power, such as Amazon EC2, for a one or three-year term. Here are some key points about Reserved Instances:

Cost Savings: You can save up to 75% compared to on-demand instance pricing.
Flexibility: RIs come in different levels of commitment. You can select standard RIs for deeper savings or convertible RIs that allow you to change the instance type.
Predictable Pricing: You pay a set amount up front or monthly, which helps with budgeting for cloud resources.

What are Savings Plans?

Savings Plans are another way to save money on AWS. They offer flexibility across AWS services. Here are some important things to know about Savings Plans:

Cost Savings: Like RIs, Savings Plans can save you up to 72% compared to on-demand pricing.
Flexible Usage: You commit to a certain amount of spending per hour across any AWS service, so you aren’t limited to specific instance types.
Variety of Options: There are two types of Savings Plans: Compute Savings Plans and EC2 Instance Savings Plans. Each type serves different needs based on your cloud usage.

Why Choose Reserved Instances and Savings Plans?

Both Reserved Instances and Savings Plans are smart choices for businesses that want to reduce their cloud costs. Here are a few reasons to consider them:

Budget-Friendly: Helps businesses stick to a budget by reducing overall AWS spending.
Long-Term Planning: Great for companies that have steady workloads and can plan ahead.
Resource Control: Gives businesses the power to manage their cloud resources more effectively.

Reserved Instances and Savings Plans are essential tools for managing cloud costs in Amazon Web Services (AWS). Understanding how they are used can help businesses optimize their AWS spending. Here’s how each is applied:

Using Reserved Instances

Predictable Workloads: Businesses that have predictable workloads benefit from Reserved Instances by reserving capacity and ensuring that they have the necessary resources available when needed. This is ideal for applications that require consistent performance.
Long-Term Savings: Companies can commit to using specific EC2 instance types for one or three years. By doing this, they can secure significant cost savings compared to on-demand pricing.
Flexibility in Instance Types: With Convertible Reserved Instances, users can change their reserved instance types if their needs change. This allows businesses to adapt to new requirements while still enjoying significant savings.

Using Savings Plans

Flexible Spending: Savings Plans give businesses more flexibility compared to Reserved Instances. Companies can commit to a certain amount of spending per hour across any AWS service, making it easier to manage varying workloads.
Cost Reduction Across Services: Organizations can apply Savings Plans to multiple services, not just EC2. This allows for better cost management across a wide range of AWS products, including Lambda, Fargate, and more.
Optimization of Resource Allocation: With Savings Plans, businesses can switch between different instance families and regions without losing their savings. This helps in optimizing resource allocation based on real-time demands.

Real-World Application

Businesses use Reserved Instances and Savings Plans to manage their AWS budgets effectively. By analyzing their usage patterns and understanding their resource needs, organizations can leverage these options to reduce overall cloud spending while ensuring that they have the necessary resources to support their applications and services.

Our Customers Say

I was at WooliesX (Woolworths) and we used Alooba and it was a highly positive experience. We had a large number of candidates. At WooliesX, previously we were quite dependent on the designed test from the team leads. That was quite a manual process. We realised it would take too much time from us. The time saving is great. Even spending 15 minutes per candidate with a manual test would be huge - hours per week, but with Alooba we just see the numbers immediately.

Shen Liu, Logickube (Principal at Logickube)

We get a high flow of applicants, which leads to potentially longer lead times, causing delays in the pipelines which can lead to missing out on good candidates. Alooba supports both speed and quality. The speed to return to candidates gives us a competitive advantage. Alooba provides a higher level of confidence in the people coming through the pipeline with less time spent interviewing unqualified candidates.

Scott Crowe, Canva (Lead Recruiter - Data)

How can you accurately assess somebody's technical skills, like the same way across the board, right? We had devised a Tableau-based assessment. So it wasn't like a past/fail. It was kind of like, hey, what do they send us? Did they understand the data or the values that they're showing accurate? Where we'd say, hey, here's the credentials to access the data set. And it just wasn't really a scalable way to assess technical - just administering it, all of it was manual, but the whole process sucked!

Cole Brickley, Avicado (Director Data Science & Business Intelligence)

I wouldn't dream of hiring somebody in a technical role without doing that technical assessment because the number of times where I've had candidates either on paper on the CV, say, I'm a SQL expert or in an interview, saying, I'm brilliant at Excel, I'm brilliant at this. And you actually put them in front of a computer, say, do this task. And some people really struggle. So you have to have that technical assessment.
