When we design a software architecture, there are lots of strategies can enhance performance, optimize cost, and simplify its effort to implement/operate the system. 


Architectural Patterns

When we design a software architecture, there are lots of strategies can enhance performance, optimize cost, and simplify its effort to implement/operate the system.  

An architectural pattern is a general, reusable solution to a commonly occurring problem in software architecture within a given context. Architectural patterns are similar to software design patterns but have a broader scope.


AWS Architecture References

Amazon Web Services is a subsidiary of Amazon that provides on-demand cloud computing platforms to individuals, companies and governments, on a paid subscription basis. The technology allows subscribers to have at their disposal a virtual cluster of computers, available all the time, through the Internet.

BEcause this infrastructure is programmable, it can react quickly.
  • Batch processing composed of job manager, job store and worker based on AWSBatch processing on AWS allows for the on-demand provisioning of a multi-part job processing architecture that can be used for instantaneous or delayed deployment of a heterogeneous, scalable "grid" of worker nodes that can quickly crunch through large batch oriented applications in place today that can leverage this style of on-demand processing, including claims processing, large scale transformation, media transcoding and multi-part data processing work.
  • Fault Tolerance & High Availability based on multi Availability zones in AWSMost of the higher-level services, such as Amazon Simple Storage Service(S3), Amazon SimpleDB, Amazon Simple Queue Service (SQS), and Amazon Elastic Load Balancing (ELB), have been built with fault tolerance and high availability in mind. Service that provide basic infrastructure, such as Amazon Elastic Compute Cloud (EC2) and Amazon Elastic Block Store (EBS), provide specific features, such as availability zones, elastic IP address, and snapshots, that a fault-tolerant and high available system
  • Large scale computing based on huge data sets in AWSThese scenarios involve huge data sets collected from scientific equipment, measurement device, or other compute jobs. After collection, these data sets need to be analyzed by large-scale compute jobs to generate result data sets. Ideally, results will be available as soon as the data is collected. Often, these results are then made available to a larger audience.
  • Advertisement serving in AWSInternet advertising services need to serve targeted advertising and must do so under limited time. These are just two of multiple technical challenges they face.

Programmatic Advertising Architecture

Traditionally programmatic advertising is also called as online advertising. Programmatic advertising includes real-time bidding as a part of its solution.


Programmatic architecture allows advertisers to deliver a personalized ad with the help of DMPs(Data Management Platforms) that store a user's information such as age, demographics, and location.

  • Programmatic advertising is the automated buying and selling of online advertising
    • This automation makes transactions efficient and more effective, streamlining the process and consolidating your digital advertising efforts in one technology platform. 
    • Targeting tactics are used to segment audiences using data so that advertisers only pay for ads delivered to the right people at the right time, and depend less on the “spray and pray” method of digital advertising


Programmatic Advertising Architecture

Note that RTB = Real-Time Bidding
