Possible disadvantages of Oracle WebLogic

• Complexity
  Due to its extensive feature set and capabilities, WebLogic can be complex to install, configure, and manage, requiring specialized knowledge and experience.
• Cost
  Oracle WebLogic can be expensive, both in terms of licensing fees and the costs associated with maintenance and support. This can be a consideration for smaller organizations or startups.
• Resource Intensive
  The platform can be resource-intensive, requiring significant hardware and computational resources to run effectively, which could be a constraining factor for some businesses.
• Learning Curve
  There is a steep learning curve associated with mastering Oracle WebLogic, which can result in longer onboarding times and additional training costs for developers and administrators.
• Vendor Lock-in
  Using Oracle WebLogic tightly integrates businesses into the Oracle ecosystem, which can lead to vendor lock-in. Migrating to a different platform could be costly and complex.

Apache ZooKeeper features and specs

• High Availability
  ZooKeeper is designed to be highly available, with built-in redundancy and failover mechanisms that ensure minimal downtime.
• Consistency
  It follows a strict consistency model, ensuring that reads reflect the most recent writes, which is crucial for coordination and configuration management.
• Scalability
  ZooKeeper can handle a high number of read operations and can be scaled horizontally by adding more nodes to the ensemble.
• Leader Election
  ZooKeeper simplifies the implementation of leader election processes, making it easier to design fault-tolerant distributed systems.
• Cluster Management
  It aids in cluster management by providing mechanisms to track the status and configuration of nodes across a distributed system.
• Watch Mechanism
  ZooKeeper provides a watch mechanism that allows clients to be notified of data changes, helping to keep state synchronized across systems.

Possible disadvantages of Apache ZooKeeper

• Complexity
  Setting up and managing a ZooKeeper ensemble can be complex, requiring careful configuration and maintenance.
• Resource Intensive
  ZooKeeper can be resource-intensive, requiring significant memory and CPU, especially in large deployments.
• Write Performance
  While read operations are very fast, write operations can be slower due to the need to achieve consensus among ZooKeeper nodes.
• Operational Overhead
  Managing ZooKeeper involves operational overhead, including monitoring, backups, and handling node failures.
• Limited Programming Language Support
  Although ZooKeeper supports many major languages, the client libraries for some languages may not be as mature or well-supported as those for others.
• Transaction Size
  ZooKeeper is not designed for very large data or complex transactions, limiting its use cases to lightweight coordination tasks.
