Today we’ll talk more about the cost tracking for serverless architecture. Following the cost of serverless architecture utilization it might give you insights on how and what should you change or adapt to, to be able to reduce the cost. After all, we’re all always trying to improve our performances in every field while keeping the costs to a minimum (if possible). Cost tracking allows you to know everything that’s happening and how much does it cost you, so you’ll be able to change and modify the presets. Learn more about the business benefits of using serverless as well as how much your AWS bill can be reduced by reading the article on this link.
Serverless architecture became the “next best thing” of computing power, and provides you with some perks you never knew you needed before:
Since AWS is continuously trying to improve the cost reduction for its customers, there is an automated solution from which you could benefit. Should you decide to utilize this solution, which is a series of AWS products, read the following:
Companies need to be thinking long-term before even starting a software development project. These needs are solved at the level of architecture: business owners want to assure agility, scalability, and performance.
The top contenders for scalable solutions are serverless and microservices. Both architectures prioritize security but approach it in their own ways. Let’s take a look at how businesses can benefit from the adoption of serverless architecture vs microservices, examine their differences, advantages, and use cases.

Any business when thinking of scaling business applications in a cost-effective way goes for a cloud computing approach. Even leading technology companies like Quora, Facebook, LinkedIn, Pinterest, and Spotify are also getting benefits offered by cloud computing infrastructures.
In this article, we are going to deeply understand the concept of serverless and how it works and why it is useful for your business.

The adaptability and flexibility of today’s cloud services present a lot of opportunities to cut infrastructure costs. Amazon Web Services and its plethora of services let you set up any kind of cloud environment for any type of application, without forcing you to make long-term commitments. At the very least, you don’t have to make a big initial investment to set up your cloud environments.
AWS resources are designed to make deploying cloud-native applications easy and affordable. Affordability is always important for businesses because cost-efficient applications guarantee higher returns on cloud investment. The way AWS services are set up allows for easy scaling of apps and cloud resource usage, but keeping your cloud environment efficient is not without its challenges.

Serverless Computing is the most promising trend for the future of Cloud Computing. As of 2020, all major cloud providers offer a wide variety of serverless services. Some of the FaaS offerings provided withing different cloud providers are AWS Lambda, Google Cloud Functions, Google Cloud Run, Azure Functions, and IBM Cloud Functions. If you want to use your current infrastructure, you could also use the open-source alternatives like OpenFaaS, IronFunctions, Apache OpenWhisk, Kubeless, Fission, OpenLambda, and Knative.
In a previous article, I iterated the most important autoscaling patterns used in major cloud services, along with their pros/cons. In this post, I will go through the process of predicting key performance characteristics and the cost of scale-per-request serverless platforms (like AWS Lambda, IBM Cloud Functions, Azure Functions, and Google Cloud Functions) with different workload intensities (in terms of requests per second) using a performance model. I will also include a link to a simulator that can generate more detailed insights at the end.
A performance model is “A model created to define the significant aspects of the way in which a proposed or actual system operates in terms of resources consumed, contention for resources, and delays introduced by processing or physical limitations” [source]. So using a performance model, you can “predict” how different characteristics of your service will change in different settings without needing to perform costly experiments for them.
The performance model we will be using today is from one of my recent papers called “Performance Modeling of Serverless Computing Platforms”. You can try an interactive version of my model to see what kind of information you can expect from it.
The input properties that need to be provided by the user to the performance model along with some default values.
The only system property you need to provide is the “idle expiration time” which is the amount of time the serverless platform will keep your function instance around after your last request before terminating it and freeing its resources (to know more about this, you are going to have to read my paper, especially the system description section). The good news is, this is a fixed value for all workloads which you don’t need to think about and is 10 minutes for AWS Lambda, Google Cloud Function, and IBM Cloud Functions and 20 minutes for Azure Functions.
The next thing you need is the cold/warm response time of your function. The only way you can get this value, for now, is by actually running your code on the platform and measuring the response times. Of course, there are tools that can help you with that, but I haven’t used them, so, I would be glad if you could tell me in the comments about how they were. Tools like the AWS Lambda Power Tuning can also tell you the response time for different memory settings, so you can check which one fits your QoS guarantees.

By this point most enterprises, including those running on legacy infrastructures, are familiar with the benefits of serverless computing:
The benefits of agility and cost reduction are especially relevant in the current macroeconomic environment when customer behavior is changing, end-user needs are difficult to predict, and development teams are under pressure to do more with less.
So serverless is a no-brainer, right?
Not exactly. Serverless might be relatively painless for a new generation of cloud-native software companies that grew up in a world of APIs and microservices, but it creates headaches for the many organizations that still rely heavily on legacy infrastructure.
In particular, enterprises running mainframe CICS programs are likely to encounter frustrating stumbling blocks on the path to launching Functions as a Service (FaaS). This population includes global enterprises that depend on CICS applications to effectively manage high-volume transactional processing requirements – particularly in the banking, financial services, and insurance industries.
These organizations stand to achieve time and cost savings through a modern approach to managing legacy infrastructure, as opposed to launching serverless applications on a brittle foundation. Here are three of the biggest obstacles they face and how to overcome them.
Middleware that introduces complexity, technical debt, and latency. Many organizations looking to integrate CICS applications into a microservices or serverless architecture rely on middleware (e.g., an ESB or SOA) to access data from the underlying applications. This strategy introduces significant runtime performance challenges and creates what one bank’s chief architect referred to as a “lasagna architecture,” making DevOps impossible.
