Describe the benefits of using cloud services Flashcards
High Availability & Scalability/Elasticity
High availability is the ability to keep services running for extended periods of time with very little downtime.
-Reduced Downtime
-Geographic Redundancy
-Load Balancing
-Automatic Failover
-Managed Services
Scalability is the ability to scale, so allocate and deallocate resources at any time. Elasticity is the ability to scale dynamically
-Elastic Resources
-Cost Efficiency
-Global Reach
-Managed Auto-Scaling
-Resource Optimization
Reliability & Predictability
Reliability means that a system, device, process, or person can be counted on to perform its intended function or deliver a specific outcome without failing or experiencing significant disruptions.
-High Uptime
-Redundancy
-Scalability
-Managed Services
Predictability is the quality of being able to forecast or anticipate outcomes, behaviors, or events with a reasonable degree of accuracy or certainty.
-Cost Predictability
-Resource Optimization
-Service Level Agreements (SLAs)
-Flexible Workloads
Security & Governance
Security and governance are crucial aspects of cloud computing that provide numerous benefits to organizations using cloud services.
Security:
-Data Protection
-Compliance
-Security Expertise
-Patch Management
-Physical Security
-Security Automation
Governance:
-Centralized Control
-Cost Management
-Resource Optimization
-Access Control
-Compliance Auditing
-Policy Enforcement
Manageability
Manageability in the cloud refers to the ease with which organizations can monitor, configure, maintain, and optimize their cloud resources and services.
-Simplified Resource Provisioning
-Automation
-Scalability
-Resource Monitoring
-Cost Management
-Security and Compliance
-Patch Management
-High Availability and Redundancy
-Data Backup and Recovery
-Collaboration and Access Control
-Resource Optimization
-Global Reach
Economies of Scale
The principle of economies of scale states that as the companies grow they become more effective at managing shared operations. Be that HR and hiring, taxes, accounting, internal operations, marketing, big purchases via contracts meaning better discounts, etc. etc.
Because of those, companies can save/earn more which in return allows for reduction in cost of their services to their customers.
Key Concepts
-Agility is the ability to react fast (scale quickly)
-Fault tolerance is the ability to maintain system uptime while physical and service component failures happen
-Disaster recovery is the process and design principle which allows a system to recovers from natural or human induced disasters
