Top 10 Devops Tools

Cassandra is from the Apache family of software products is a NoSQL database solution that provides its users the ability to store humongous amounts of data (be it structured or unstructured data).

In the Big-data scenario – Cassandra fits into the structured storage category and becomes the only alternative for additional storage options. Facebook has made Cassandra an open-source application in 2008 which combines distributed technologies from Amazon Dynamo key-value store and Google BigTable column-based data model to achieve what it is today.

One of the greatest abilities of Cassandra is to scale across multiple data centers in the cloud. Netflix has completely taken advantage of Cassandra’s decentralized model and also its replication strategy to span its deployments across multiple AWS availability zones for resiliency to avoid further outages like the infamous AWS outage that ned on 22nd October 2012.

Following are some of the advantages of using Cassandra, let us now take a look at each and every one of them:

Advantages:

• Dynamo and BigTable made modeling of complex data structures simple which would have been difficult in the traditional RDBMS world.
• It Caters and Provides a plethora of data modeling use cases.
• No single point of failure – data is distributed across various clusters.
• If the replication strategy is set right, individual node failures can be handled with no downtime.
• Data on the cluster is distributed across the nodes and further addition of nodes brings down the possibility of failures – handles the load efficiently as well.
• The icing on the cake is the out-of-the-box Hadoop integration from 2010.

• Faster and safer replications and can be managed in parallel as well.
• Indexes for the heap memory engine are done considerably faster.

7. OrientDB:

OrientDB is an open-source NoSQL database management system that was written in Java. Alternatives to RDBMS have been existent for many years but they have been used primarily in use cases such as Telecommunications, Medicine, CAD, etc.

Not a surprise, but the larger web application giants like Google, Facebook, LinkedIn, Amazon and etc. have been using NoSQL-based solutions for their production environments.

It is a document-based database but the relationships are managed as a graph rather than the relationships in tables. It is a disseminated Graph Database engine with the pliability of a Document Database rolled into one NoSQL database.

There are many areas that the traditional RDBMS haven’t been able to cater but these NoSQL databases like OrientDB were able to answer – such as Performance, Scalability, Smaller footprint, Flexibility in Schemas.

Following are some of the advantages of using OrientDB, let us now take a look at each and every one of them:

Advantages:

• The provision of well-documented documentation helps beginners to grasp graph theory and OrientDB practices.
• Since it is built on Java, customizing various implementations on demand should be something that you can experiment with.
• It has a very easy installation process for the database.
• Its close resemblance to relational SQL renders it very easy for the developers to adopt.
• The outcomes of these queries are given extremely fast.
• This database becomes very unique as it has both the document and graph database features.
• Embedded maps make it very useful.

8. HBase:

HBase is a freeware, multidimensional, distributed, and scalable NoSQL database written in Java. HBase works on the apex of HDFS (Hadoop Distributed File System) and facilitates capabilities like BigTable to Hadoop. It is developed to facilitate a fault-tolerant method of storing a large number of sparse data sets. As HBase achieves high throughput and low latency by providing fast Read/Write Access to huge datasets, it is the best choice for the applications which require fast & random access to a large amount of data. It provides compression, in-memory operations, and Bloom filters (data structure which tells whether a value is present in a set or not) to fulfill the requirement of fast and random read-writes.

Following are some of the advantages of using HBase, let us now take a look at each and every one of them:

Advantages:

• The capacity, storage, and processing of bulk data are carried out robustly.
• Flexible schema as we can add an “n” number of attributes in a column family at runtime without declaring them at the time of table creation.
• Fault tolerance- As we know MapReduce runs internally for all kinds of operations, In case of failure scenarios mapper and reducer job handles it.
• Versioning of records- The default feature for versioning is available. If that is enabled, HBase updates the record and also keeps the old record data.
• It is considered to be a powerful NoSQL tool, which helps in data management, and eases retrieval and manipulation of the same data.
• It is better than the traditional file system, because of the efficiency, which it provides for the same amount of system, and the major advantage is that the utilization of commodity hardware, to store the data.
• Also, it is fault-tolerant, as it keeps a replica of the data stored, so in case of failure, the replica can be used.

9. Couchbase:

Couchbase is a NoSQL database that is specifically engineered to meet the ever-changing needs of the business to scale and to provide high performance consistently and also with a track record to be always reliable and available.

These are nothing but the data mobility requirements of any high-performance applications. Having said that, the following are the best possible features that tend to define the DevOps strategy in the database world, namely – 1) Schema flexibility, 2) No impedance mismatch,  3) Scalability.

NoSQL document databases like Couchbase provide the schema flexibility to the developers to operate over the JSON directly and lets them derive meaning out of it.

As the developers are allowed to decide upon the JSON structures, curtails the need for any ORM technology as well and hence cuts down the impedance mismatch between the domain classes of the database structure.

NoSQL databases run on the convention of scaling up to the needs of the businesses that demand it and hence ensures Scalability is delivered from the day it is chosen and hence proves trustworthy over the traditional RDBMS database technologies.

Following are some of the advantages of using Couchbase, let us now take a look at each and every one of them:

Advantages:

• It provides a homogeneously distributed architecture with no masters and slaves.
• Provides a SQL-like query language to query the JSON documents.

• Works with an extraordinary architecture that ensures the reduction of a need for an additional caching layer.
• Provides multiple SDKs and eases cross data center replication.
• It is easy to implement and configure.
• Command-line tools are easy to use for ad-hoc tasks. 
• Least maintenance from the administration perspective.
• Latency compensation. No need to worry about network latency and stability - every action can be stored on a local DB, which will be synced automatically to the main DB when the network is available.
• Ability to develop "optimistic" UIs. No need for "loading" a spinner on every user action,  just store on a local DB, and the changes will propagate to the main DB ASAP.

10. ArangoDB:

It is a native multi-model database system that is developed by an organization that supports three important data models – Key/Value, Documents, and Graphs. All of this comes with a simple and yet powerful Unified query language called the ArangoDB Query Language (AQL) which is more or less similar to traditional SQL.

This query language, AQL is declarative in syntax and also allows the combination of different data access patterns in a single query to access the data present in the database.

It is a distributed, free NoSQL database with a flexible data model for documents, graphs, and key-value pairs as mentioned above. It finds its usage in applications that are driven with high performance using the traditional SQL like query language and/or JavaScript extensions.

Following are some of the advantages of using ArangoDB, let us now take a look at each and every one of them:

Advantages:

• AragonDB has got great backing from its community which is really helpful.
• The AQL query language that is supported by the database is really very easy to use and yet powerful.
• AragonDB lets you choose any of the use-cases and also lets you replace an existing database without much difficulty.
• It has the ability to act as a schema-less document store or as a graph database through the RDBMS features like JOINS.
• It provides HTTP REST Endpoints and also provides GraphQL.
• Provides a multi-model approach which is great and at the same time enables an individual to fulfill all the project requirements with just one database product.
