Service Level Agreements (SLAs)

SLAs outline what you can expect from your provider. They cover uptime, performance, and support. Check the guaranteed uptime percentage. 99.9% is common, but higher is better. Know what compensation you get if they fall short.

Look at their support options. Do they offer 24/7 help? What are their response times for different issue levels? Consider their maintenance schedules. Planned downtime should align with your low-usage periods to minimize disruption.

Security in the Cloud

Cloud security protects data and systems in online environments. It uses many tools and methods to keep information safe from threats.

Risk Management

Cloud providers work to spot and fix security problems. They use special software to check for weak points in their systems. This helps stop hackers before they can cause damage.

Teams also make plans for what to do if something goes wrong. These plans help companies act fast to protect data and keep things running. Regular updates to software and systems are important too. These fixes patch holes that bad actors might try to use.

Data Encryption

Cloud infrastructure uses encryption to scramble data. This makes it hard for anyone who shouldn't see the information to read it. There are two main types of encryption:

• At rest: Data is encrypted when it's stored

• In transit: Data is encrypted when it's being sent

Strong encryption keys are needed to unlock the data. Only people with the right keys can see the information.

Identity and Access Management

This part of cloud security controls who can use what in the system. It's like having a guest list for a party. Some key features:

• Multi-factor authentication

• Single sign-on

• Role-based access control

These tools ensure that only the right people can access sensitive data. They also track who does what in the system. Regular checks of who has access help keep things secure. Old accounts get removed, and permissions are updated as needed.

Impact of Cloud Computing on Industry

Cloud computing has changed how businesses work. It makes things faster and cheaper for many different types of companies.

Healthcare Sector

Cloud computing helps doctors and hospitals take care of patients better. They can store and share medical records safely online. This means doctors can see a patient's history quickly, even if they're at a different hospital.
