Hadoop deployment

Hadoop deployment means settingup hadoop cluster physically.Generally the companies startup with trial hadoop setup to check the feasibility of hadoop cluster for data processing. This is known as the phseodo distributed mode.

Advantages

• Storage
• fault tolerance
• flexibility
• low cost
• scalability

Disadvantages

• Not fit for small data

• Program model is restrictive
• joins of multiple databases is complex and slow

Public cloud
