The document outlines the technical and business considerations organizations must evaluate before adopting cloud computing, highlighting important factors such as bandwidth, latency, and the selection of cloud carriers and providers. It discusses risks associated with service level agreements (SLAs), the challenges of cloud migration, and the need for network security and operational governance. Additionally, it touches upon legal issues related to data storage and privacy across different jurisdictions.
BUSINESS CONSIDERATIONS FOR CLOUD COMPUTING
- 1. TECHNICAL AND BUSINESS CONSIDERATIONS FOR ADOPTION CLOUD COMPUTING Dr Hitesh Mohapatra Associate Professor
- 2. BUSINESS CONSIDERATION FOR CLOUD COMPUTING • There are technical and business considerations organization needs to take into accounts before adopting cloud computing technology. • There is several technical and business considerations of on-premise deployment models and cloud base IT resources model that meet business needs. • Before any recommendations of moving to a cloud-based IT resources, several technical issues, cost and network expenditure, Cloud model, network bandwidth and latency Issues, connectivity issues and cloud carrier and cloud provider selection.
- 3. Connectivity Issues • Traditional on-premise deployments models for enterprise and businesses are mostly hosted on a private centralize servers storage devices residing in the organizations and business own data center. • TCP/IP facilitates both internet access and uninterrupted internet connectivity for on-premise data exchange over LANs for data center through the corporate networks for end-use devices (smartphones, tablets, laptop and PC's). • Geographical distance between cloud consumer and the cloud provider can also be considered as longer distance can require additional network hops but can also introduced potential bandwidth and fluctuating latency constraints.
- 4. Cont. The diagram below shows the configuration implementations for an internetworking architecture of a private cloud model with an on-premise data exchange networks of over the LANs. The physical IT resources that constitute the cloud are located and managed within the organization.
- 5. Network Bandwidth and Latency Issues
- 6. Cont. • End-to-End Bandwidth: Determined by transmission capacity of shared data links. • Impact of ISP Connection: Bandwidth can be affected by intermediary nodes connecting networks to ISPs. • Broadband Network Technology: ISPs must implement broadband technology in the core network to ensure end-to-end connectivity.
- 7. Cont. • Latency Considerations: Time delay (latency) needs to be reduced for network efficiency. • Web Acceleration Technologies: Dynamic caching, compression, and prefetching are driving the need to improve end-user connectivity and Quality of Service (QoS). • Packet Switching: Allows data packets to dynamically choose their path, impacting end-to-end communication and QoS.
- 8. Cont. • Cloud Bandwidth & Latency: Critical for cloud provisioning, as bandwidth impacts data transfer, and latency affects application response times and QoS. • Business Requirements: Organizations need to assess bandwidth and latency when moving IT solutions to the cloud to meet business needs effectively.
- 9. Other challenges to consider in cloud computing
- 10. Cloud Carrier and Cloud Provider Selection • Importance of selecting the right cloud carrier and provider • Service Level Agreements (SLAs) ensure proper internet connections, QoS, and network paths • Multiple ISPs help meet business needs through improved connectivity and reliability • Multiple cloud carriers enhance cloud application performance and QoS but increase costs • Risks of unreliable cloud providers failing to meet SLA guarantees • Impact of poor SLA compliance on cloud consumer solutions
- 11. Cloud IT resources Cloud Deployment Model •Organizations can utilize their cloud deployment model over the internet. •IT operations are maintained while safeguarding corporate networks. •Firewall and monitoring software ensure network security. Advantages of Cloud for End-Users •Centralized IT resources accessible via the internet. •Same protocol used for access, whether resources are inside or outside the corporate network. Continuous Access to Cloud Resources •Centralized servers and applications are continuously accessible through the internet.
- 13. A comparison between a On-Premise IT Resources and a Cloud-Based IT Resources
- 14. Challenges and risk in Cloud Computing Adoption
- 15. Cloud Carrier and Cloud Provider Selection Service Levels of Internet Connections •Determined by different ISPs between cloud consumers and providers •Involves multiple ISP networks in their paths Challenges in QoS Management •Difficult to manage across multiple ISPs •Requires collaboration between cloud carriers Impact on Cloud Connectivity •Cloud consumers and providers may need multiple cloud carriers •Ensures necessary connectivity and reliability for cloud applications •Results in additional costs Cloud Adoption Considerations •Easier for applications with relaxed latency and bandwidth requirements
- 16. Reduced Operational Governance Control • Reduce Operational governance control provided for cloud consumers are usually lower than than of on-premise IT resources. • This reduced level of governance operational control on cloud can introduce risks that is associated the provisioning of cloud and how it operates by the cloud providers.
- 17. Limited Portability Between Cloud Providers • Lack of Industry Standards: Public clouds lack established industry standards, leading to issues related to ownership and control. • Challenges in Cloud Migration: Cloud consumers using custom-built solutions face difficulties when switching from one provider to another. • Portability Definition: Portability measures the impact of moving IT resources and data between cloud providers. • Decreased Portability: The diagram shows how cloud consumer (A) experiences reduced portability during a migration between cloud (A) and cloud (B). • Security Technology Mismatch: Portability is affected as cloud (B) does not support the same security technologies as cloud (A).
- 19. Multi-Regional Regulatory and Legal Issues •Geographical location preferences: Data centers are often established in affordable and convenient locations. •Legal concerns: Cloud providers must consider data privacy and storage policies to comply with industry and government regulations. •Data residency requirements: For instance, UK laws mandate that personal data of UK citizens be stored within the country. •Data accessibility issues: Different countries have varying laws regarding data disclosure to government agencies. •Example - U.S. Patriot Act: U.S. government agencies can access cloud consumer data (including European data) stored in the U.S., unlike data located in other EU countries.
