Study Notes
Limitations and Challenges in Cloud Computing
- Monitoring in cloud computing may face limitations due to the complexity of distributed systems and dynamic resource allocation.
- Network bottlenecks can occur when multiple users access the same bandwidth-intensive resources, leading to slower data transfer and increased latency.
- Outages can severely damage the reputation of cloud service providers, affecting customer trust and potentially resulting in financial losses.
- Business risks not covered by a cloud SLA can lead to unforeseen expenses, compliance issues, or reputational harm for organizations.
Federated Service Level Agreements (SLAs)
- A characteristic of federated SLAs is that they facilitate agreements across multiple service providers, enabling interoperability and resource sharing.
Negotiations and User Challenges
- Negotiations with large cloud providers can be difficult for small users due to their limited bargaining power and the predominance of pre-defined, one-size-fits-all agreements.
- Common challenges in cloud computing include data security concerns, compliance issues, and vendor lock-in scenarios.
Composability and Customization
- A key characteristic of a composable component is its modularity, allowing it to be easily replaced or upgraded without affecting overall system functionality.
- Cloud computing impacts system customization by providing flexible resources that can be tailored to specific business needs, though it may also introduce limitations based on provider offerings.
Data Stores and Bandwidth
- Large data stores in cloud environments can impact bandwidth connections by requiring significant data transfer capacity, potentially overwhelming existing network infrastructure.
Storage Types and Vendor Lock-in
- Scalable storage options typically offer low performance due to high latency and access times, making them suitable for large amounts of data rather than high-speed retrieval.
- Vendor lock-in is highest in proprietary cloud models, where users become dependent on a specific provider's tools and services.
The Cloud Computing Stack and Custom Application Development
- 'The Cloud Computing Stack' is likened to a layered architecture, encompassing various service tiers that build on one another, creating a structured framework for cloud services.
- Custom web application development is supported by Infrastructure as a Service (IaaS), which provides needed hardware and software resources.
Platform vs. Virtual Appliance
- The key difference between a platform and a virtual appliance is that a platform offers a broader environment for application development, while a virtual appliance is a pre-configured software environment designed for a specific task.
Adoption Trends and Security in the Cloud
- Top business types adopting cloud computing include tech companies, healthcare organizations, and financial institutions, reflecting a diverse range of industries.
- Additional security methods to ensure data privacy in the cloud include encryption, multi-factor authentication, and regular security audits.
Web Services and Communication Protocols
- Most Web services stacks are built on the principles of SOA (Service-Oriented Architecture), allowing for flexible integration and interaction between services.
- SOAP messaging typically utilizes the XML-based communication protocol for service discovery and operation description.
- WSDL (Web Services Description Language) enables a web service to advertise its capabilities by providing a machine-readable format detailing available methods and data formats.
Connecting to the Cloud
- REST (Representational State Transfer) is a common standard for data interchange in cloud computing, emphasizing stateless communication.
- The medium over which data exchange occurs in cloud connections is characterized by its ability to transmit data efficiently over the Internet.
