Questions & Answers

Q: What are the main disadvantages of on-premise systems for scaling a software development firm?

On-premise systems have higher costs, limited scaling options, and require extensive infrastructure and maintenance, which can lead to heavy losses when scaling down.

Q: How do cloud computing solutions address the limitations of on-premise systems?

Cloud computing allows you to pay only for what you use, offers faster and easier scaling options, eliminates the need for server storage and maintenance, and provides better data security and disaster recovery measures.

Q: What are the advantages of cloud computing in terms of data security?

Cloud computing systems offer better data security compared to on-premise systems, as they have robust security measures in place and avoid the need for constant monitoring and management of security protocols.

Q: How does cloud computing reduce maintenance costs for businesses?

Cloud computing systems are maintained by the cloud service providers, which reduces costs and resource allocation for hardware and software maintenance that is required for on-premise systems.
