Cloud Computing platforms comprise of a large number of individual services that work in a very complex yet synchronized manner. These services collectively handle separate tasks that run your website or app.

An e-commerce website hosted on AWS may utilize EC2 instances, Elastic load balancers (ELBs), CloudFront, AutoScaling, S3 and many other services of AWS for an optimal performance. A selection of these services in a proper mix to yield desirable computing power for your business is called the Cloud Computing Architecture.

When we say desirable computing power it simply means, putting enough services that provide glitch-free performance to your website or app while spending as less as possible. However, to figure out a proper mix of these services for your project, you need a professional cloud architecture company. This is where OpenXcell comes in.

As we know that cloud computing platforms are comprised of a large number of individual services, we will list a few common services of these for your understanding. Please note that these are very common and often appear in any architecture.


Elastic Cloud Compute house the instances that provide flexible computing abilities in the cloud.


An EC2 instance is a virtual server in Amazon’s Elastic Compute Cloud (EC2) for running applications on the Amazon Web Services (AWS) infrastructure.

Elastic Load Balancers (ELBs):

Elastic load balancers Elastic load balancer (ELB) is a load balancing solution that automatically scales its request-handling capacity in response to incoming application traffic.


S3 is nothing but Simple Storage Solution provided in AWS. S3 is used to store static content of your app or website and distribute it when needed.


Cloudfront or CDN is a content distribution service that may work on top of S3 in many cases. A CDN caches and proxies data into the edge locations. In other words, CDN facilitates data access with greater speeds.


Elasticache enables in-memory caching. This helps to build features that require real-time data such as Leaderboards and Stock Market tickers.


Autoscaling starts and terminates instances automatically with respect to the volume of incoming traffic it is receiving at any given time.

There are other services for databases such as DynamoDB,Amazon redshift, and Amazon RDS. Overall, these constitute as some of the major services we come across in AWS. As far as google and Azure are concerned, they have similar services as well.

What are the factors that Architecture Consultants consider before sketching out the configuration for your project?

Number of Users and Requests:As for startups, our consultants commonly rely on a relational DB coupled with M1 or M2 instances. However, a larger number of users generating a lot of requests may work well with NoSQL and compute-optimized instances such as a C1 or CC2. If the app generates a lot of requests throughout the globe, then our specialists may also put CloudFlare and a load balancer to this mix.

Type of App and Traffic:

Type of app may directly affect the selection of instance type. Running an analytic app may require a compute-optimized instance while running an e-commerce marketplace may ask for storage optimized instances.

Periodic traffic with fewer fluctuations might require a slim architecture with less need for edge locations. On the other hand, sites with fluctuating traffic might require access to more edge locations along with Autoscaling and more load balancing.

Static vs. Dynamic Content:

Hosting static content is less expensive for obvious reasons. On the other hand dynamic content needs more resources which increases the cost. Our consultants put the S3 into use when a lot of static assets such as CSS, images, PDFs, Videos, logs etc are there.

Need for Horizontal vs. Vertical Scaling:

Vertical scaling is simply opting for larger machines with higher processing power. Vertically scaled apps generally run like a giant monolithic app. This is not recommended in many cases. If you have a large number of services running for your app, you should instead opt for horizontal scaling. Our architecture consultants will guide you to select the right one according to your needs.

Requirement of Microservices:

Microservices are nothing but individual services within your app that are segregated and made to run in isolation. Often, this is enabled by container as a service technologies such as Docker. Microservices helps you to speed up your DevOps and reduce implementation time. Depending on the type of app and physical location(s) of your development team(s), our experts will sketch out an appropriate IaaS and PaaS configuration.

While there are a number of other factors,  the aforementioned services come out as the major ones all the time. After we receive a complete set of requirements for your app, we send you a tentative architecture, to begin with. Depending on how your business grows, we scale up your architecture striking a balance between performance and cost.
