Architecture Software Interview Questions

What Is CAP Theorem?

The CAP Theorem for distributed computing was published by Eric Brewer. This states that it is not possible for a distributed computer system to simultaneously provide all three of the following guarantees:

  • Consistency (all nodes see the same data even at the same time with concurrent updates )
  • Availability (a guarantee that every request receives a response about whether it was successful or failed)
  • Partition tolerance (the system continues to operate despite arbitrary message loss or failure of part of the system)
  • The CAP acronym corresponds to these three guarantees. This theorem has created the base for modern distributed computing approaches. Worlds most high volume traffic companies (e.g. Amazon, Google, Facebook) use this as basis for deciding their application architecture. Its important to understand that only two of these three conditions can be guaranteed to be met by a system.

    5 beginner software architect interview questions and answers

    In this section, you’ll find answers to five of the software architect interview questions above that you should be listening out for from your candidates.

    What do software architects do?

    Software architects are expert, professional developers who share information between software engineering teams and clients to implement precise software design solutions. Some of their primary responsibilities are:

  • Project code QA testing
  • Task distribution for software engineer teams
  • Technical standards evaluation
  • Breaking down project goals into deliverable tasks
  • KISS means “keep it simple, stupid.” In the software architect field, KISS implies that a system will function best when a developer or architect takes a simple approach to designing. It suggests that architects should avoid complex designs.

    What do you mean by lower latency interaction?

    Low latency means that there is very little delay between the time you request something and the time you get a response. As it applies to webSockets, it just means that data can be sent quicker (particularly over slow links) because the connection has already been established so no extra packet roundtrips are required to establish the TCP connection.

    5 tips to consider when using software architect interview questions

    There are five vital tips that you should consider when using software architect interview questions. We have listed them below.

    What Is Load Balancing?

    Load balancing is simple technique for distributing workloads across multiple machines or clusters. The most common and simple load balancing algorithm is Round Robin. In this type of load balancing the request is divided in circular order ensuring all machines get equal number of requests and no single machine is overloaded or underloaded.

    The Purpose of load balancing is to

  • Optimize resource usage (avoid overload and under-load of any machines)
  • Achieve Maximum Throughput
  • Minimize response time
  • Most common load balancing techniques in web based applications are

  • Round robin
  • Session affinity or sticky session
  • IP Address affinity
  • Explain what cohesion means in software architecture.

    When software architects divide a system into modules, cohesion measures the extent to which all elements that belong to the module are functionally related. Some of the main types of cohesion include:

  • Communicational cohesion
  • Functional cohesion
  • Sequential cohesion
  • Procedural cohesion
  • Temporal cohesion
  • Logical cohesion
  • Coincidental cohesion
  • Software Architect qualifications to look for

    Software Architects participate in the entire software development lifecycle so that it integrates seamlessly with existing platforms.Â

    Your best candidates will have coding skills in various languages and the ability to work on complex tasks. Hands-on experience is a must, and they should have an ample portfolio to show off.

    It’s a good idea to put your candidates’ skills to the test by providing an assignment during the interview process. Â
