Hadoop features and specs

• Scalability
  Hadoop can easily scale from a single server to thousands of machines, each offering local computation and storage.
• Cost-Effective
  It utilizes a distributed infrastructure, allowing you to use low-cost commodity hardware to store and process large datasets.
• Fault Tolerance
  Hadoop automatically maintains multiple copies of all data and can automatically recover data on failure of nodes, ensuring high availability.
• Flexibility
  It can process a wide variety of structured and unstructured data, including logs, images, audio, video, and more.
• Parallel Processing
  Hadoop's MapReduce framework enables the parallel processing of large datasets across a distributed cluster.
• Community Support
  As an Apache project, Hadoop has robust community support and a vast ecosystem of related tools and extensions.

Possible disadvantages of Hadoop

• Complexity
  Setting up, maintaining, and tuning a Hadoop cluster can be complex and often requires specialized knowledge.
• Overhead
  The MapReduce model can introduce additional overhead, particularly for tasks that require low-latency processing.
• Security
  While improvements have been made, Hadoop's security model is considered less mature compared to some other data processing systems.
• Hardware Requirements
  Though it can run on commodity hardware, Hadoop can still require significant computational and storage resources for larger datasets.
• Lack of Real-Time Processing
  Hadoop is mainly designed for batch processing and is not well-suited for real-time data analytics, which can be a limitation for certain applications.
• Data Integrity
  Distributed systems face challenges in maintaining data integrity and consistency, and Hadoop is no exception.

IPFS features and specs

• Decentralization
  IPFS operates on a peer-to-peer network, reducing dependency on central servers and improving resilience and fault tolerance.
• Content Addressing
  Resources in IPFS are accessed through content hashes, ensuring data integrity and authenticity by directly referencing content, not its location.
• Improved Load Distribution
  By distributing data across multiple nodes, IPFS can balance load, which can improve availability and access speed.
• Offline Access
  Data stored in IPFS can be accessed offline if the content is already cached locally, enabling persistent availability.
• Resistance to Censorship
  Decentralization makes it harder to censor content since there is no single point of failure that can be targeted.
• Reduced Bandwidth Usage
  IPFS can save bandwidth by referencing previously downloaded content from local networks or peers rather than fetching it from remote servers.
• Historical Versioning
  IPFS can keep track of historical versions of content, allowing for content versioning and retrieval of past data states.

Possible disadvantages of IPFS

• Complexity
  Implementing and managing an IPFS network can be complex, requiring understanding of peer-to-peer networking and content addressing.
• Initial Content Distribution
  Uploading content to IPFS and ensuring it gets distributed across the network can require significant initial effort and time.
• Storage Redundancy
  Data is stored redundantly across multiple nodes, which can lead to increased storage requirements compared to traditional centralized storage.
• Persistence
  Unless explicitly pinned, content might not persist indefinitely on IPFS, potentially leading to loss of data that's not sufficiently replicated.
• Scalability of Pinning Services
  To ensure data persistence and availability, pinning services might be required, which can incur additional costs and complexity as the network scales.
• Legal and Compliance Issues
  Decentralized storage can complicate legal compliance and content moderation, as it's harder to control and regulate distributed data.
• Performance Variability
  Access speeds can vary based on the availability and performance of peers in the network, leading to inconsistent user experiences.
• Energy Consumption
  Maintaining a large, distributed network of nodes can lead to higher energy consumption compared to centralized infrastructure.
