Akash Network: A Decentralized Alternative to Traditional Cloud Providers

The rapid growth of artificial intelligence has significantly increased global demand for computing infrastructure. As data-intensive applications become more common, the need for accessible, scalable

The rapid growth of artificial intelligence and data-intensive applications has significantly increased global demand for computing infrastructure. However, a significant portion of this infrastructure remains idle, while developers and researchers struggle to access the resources they need.

The market for cloud computing is currently dominated by a few large providers, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud, Together, these centralized cloud providers control more than 60% of the global computing resources, leaving a highly concentrated market with limited competition and high costs for users.

Enter Akash Network, a decentralized cloud computing marketplace that aims to provide a more accessible, affordable, and scalable alternative to traditional cloud providers. By leveraging the principles of blockchain technology and a community-driven approach, Akash is revolutionizing the way we think about and interact with cloud infrastructure.

Centralized cloud providers have come to dominate the market, with AWS, Microsoft Azure, and Google Cloud being some of the major players. This centralized model introduces several challenges:

These limitations highlight the need for a decentralized and cooperative approach to cloud computing.

Decentralized cloud solutions offer several advantages over traditional models, but they also present unique challenges. Many decentralized providers struggle with fully utilizing their available resources, leading to idle infrastructure and wasted potential. Moreover, the lack of a standardized on-demand marketplace exacerbates these issues, resulting in inconsistent deployment processes and a fragmented user experience for clients.

Despite the promising potential of decentralized cloud solutions, these challenges hinder their widespread adoption. To realize the full benefits of a decentralized cloud ecosystem, it is crucial to develop efficient coordination mechanisms, seamless integration with existing developer tooling, and a deep understanding of the evolving needs of the decentralized application landscape.

Akash Network is a decentralized, open-source marketplace for cloud computing that connects clients needing computing power (tenants) with providers offering spare resources. It provides a cost-effective, secure, and scalable alternative to traditional centralized cloud providers like AWS, Microsoft Azure, and Google Cloud.

Akash aims to solve the problems of existing decentralized cloud providers by combining the best aspects of centralized and decentralized models. It introduces a new blockchain token, a flexible service definition language, and a novel reverse-auction mechanism to create an efficient and competitive market for cloud resources.

At the heart of the Akash Network lies a simple yet powerful concept: to enable anyone with idle computer resources to become a provider and those needing computing power to become a tenant. This creates a decentralized ecosystem where both parties can benefit.

The architecture of the Akash Network is built on three key components:

The Akash marketplace is a decentralized cloud platform that uses a unique approach to match clients with providers offering spare compute through a reverse auction.

Clients needing computing resources, referred to as tenants, begin by creating a Service Definition Language (SDL) file. This file acts as a blueprint for the client's requirements, detailing the desired resources and deployment parameters.

The SDL file is written in a YAML format and includes specifications such as:

Once completed, the client posts the SDL file to the Akash blockchain as an order, making the requirements visible to all resource providers in the network.

Providers, on the other hand, have the option to register their available computing resources on the blockchain. These resources are described in terms of resource units (RUs), where 1 RU is equivalent to 1 vCPU, 1 GiB of RAM, and 100 GiB of persistent storage.

As providers come online, they search for orders that match their capabilities and begin bidding on them in a competitive reverse auction. In this auction, providers bid to offer the lowest price while still meeting the client's minimum specifications.

After providers submit their bids, the client can view and evaluate them based on price, the provider's ability to meet the minimum requirements, and any additional preferences the client may have.

After selecting a provider, the client creates a lease on the blockchain to finalize the agreement. This lease is an immutable record of the terms of service between the client and provider, including the types and amounts of resources being leased, the lease duration, and the price per epoch (a time period on the blockchain).

Once the lease is finalized, the provider allocates the requested resources and deploys the client's containerized application. Akash handles orchestration tasks such as configuring networking, storage, and runtime parameters to ensure the application launches successfully.

Following deployment, Akash continues to manage the workload by monitoring resource usage, automatically scaling capacity as needed, and maintaining uptime throughout the lease period. This lifecycle management ensures stable performance and efficient utilization of decentralized infrastructure.

The Akash marketplace uses blockchain technology to ensure transparent, secure, and verifiable transactions. All payments are made in AKT, the native token of the Akash Network. A "take fee" is collected from each lease—10% of the lease price for AKT payments and 20% for other tokens—which is distributed to the network stakers through the Take Income Pool. This structure incentivizes staking and
