Hosted Applications and Virtual Servers

Cloud computing platforms leverage always-on Internet connections to combine the best aspects of local device-specific application software with massive remote mainframe-style computing power.  Many popular consumer and business applications, such as Google Maps and Twitter, appear to be just a user-friendly iOS or Android app but are as powerful as they are because they don't try to include all of their data or application logic on the device. In this way, a scalable infrastructure "in the cloud" is able to quickly draw from distributed databases to meet user needs in real time, often with artificial intelligence in the mix as well. Barr Group is in the business of designing reliable and secure computers and we have software engineers with hands-on experience in cloud technologies such as:​

  • Amazon Web Services (AWS)
  • Google Cloud Platform (GCP)
  • Microsoft Azure cloud services
  • Server virtualization and infrastructure scaling
  • Cybersecurity and network security/protocols
  • Distributed databases and elastic storage
  • OSI network layering and TCP/IP Internet protocols
  • Client/server applications and 3-tiered architecture
  • Internet of Things (IoT) devices and edge computing
  • Software-as-a-Service (SaaS)
  • Platform-as-a-Service (PaaS)
  • Infrastructure-as-a-Service (IaaS)

Barr Group's software experts are familiar with all of the major cloud computing technologies as well as related APIs from SOAP to REST and also with the programming languages used to develop cloud-hosted websites and apps, including Java, Node.js, Ruby, Scala, ASP.NET, Python, Perl, and PHP.
