Metal to Cloud: Outsmart Cloudflare, Netlify, and Vercel in Minutes

In the realm of software infrastructure, there exists a clear demarcation: platforms that are developer-centric and self-serving, and those that are not. This distinction is what sets apart industry leaders, including both established hyperscalers and companies like Cloudflare, Fastly, Vercel, & Netlify. While challenging the dominance of hyperscalers might seem daunting, competing effectively against the likes of Cloudflare and its peers is not only feasible but within reach. The reason? You likely possess the hardware—potentially superior and more geographically diverse than theirs. The key ingredient missing is a developer-friendly, self-serving platform. Traditionally, crafting such a platform demanded years and significant investment in skilled engineering talent. However, I’m here to guide you through an alternative pathway that can swiftly bring you online and ensure production readiness.

As the founder of Taubyte, I am driven by the vision to democratize cloud computing, making it as accessible as possible. Achieving this vision entails developing infrastructure software that’s easy to deploy and maintain. An added bonus in our approach is our commitment to preventing vendor lock-in; hence, our core technology is open-sourced. Our mission is not just about providing tools but ensuring that these tools are readily accessible, ensuring freedom and flexibility for developers everywhere.

Observing the technological fortresses erected by Fastly, Vercel, Cloudflare, and others can indeed be daunting. They’ve amassed vast codebases and teams of skilled engineers dedicated to constant improvement and maintenance. However, the sheer size of their infrastructure also presents a significant challenge—it’s not easy to pivot quickly or innovate in ways that might render their existing systems obsolete due to internal inertia.

Enter the simplest incarnation of a Taubyte Cloud, we call dreamland, which runs directly on your computer.

Start by installing it with the following command:

$ npm i @taubyte/dream

With the dream command-line tool now at your disposal, let’s initiate your personal cloud:

$ dream new multiverse
[INFO] Dreamland ready
[SUCCESS] Universe blackhole started!

Any ERROR messages related to seer can be disregarded at this stage.

The SUCCESS notification confirms the operational status of your cloud. Proceed by navigating to console.taubyte.com and selecting the Dreamland button to interact with your new cloud environment.

This button becomes interactive only when Dreamland is detected.

Next steps involve the web console’s sidebar: (1) select Network, followed by (2) blackhole.

Shortly, you’ll be presented with a view resembling the following:

What you’re witnessing is a constellation of virtual nodes, together forming a Cloud Computing Platform. This platform is equipped for serverless computing, web hosting, storage solutions, databases, pub-sub mechanisms, and much more.

Remarkably, this cloud is immediately available for developer engagement, accessible either via the command-line or the Web Console.

For an in-depth exploration of Dreamland and the Web Console, I recommend delving into the Introduction to Taubyte, an essential read.

Every Taubyte Cloud is associated with a Fully Qualified Domain Name (FQDN). Essentially, you can use any domain or sub-domain that you control. For instance, I’ve chosen enterprise.starships.ws for Starship Enterprise’s Web Services.

Developers often require a temporary sub-domain for testing purposes. You’re free to use a sub-domain of your main domain or opt for an entirely different one. While g.enterprise.starships.ws or el.starships.ws are valid options, my passion for Sci-Fi inspires me to select e.ftll.ink (Enterprise’s Faster Than Light Link).

The choice of infrastructure is yours to make. The only requirement is hosts (either bare metal or VMs) running Ubuntu 22.04. While any number of hosts can work, I recommend starting with three, each equipped with:

• A public IP
• +8GB of RAM

For demonstration purposes, I quickly provisioned 3 VMs across various locations:

Name	Location	IP
host-001-enterprise-starships-ws	Iowa	34.133.173.124
host-002-enterprise-starships-ws	Toronto	34.130.131.76
host-003-enterprise-starships-ws	Los Angeles	35.235.122.141

Note: This cloud setup is temporary and will eventually be decommissioned. However, it will remain accessible for testing by developers for as long as it’s operational.

Ensure the following ports are open to facilitate communication and service delivery:

Ports	Protocols	Description
4242, 4247, 4252	TCP	For Peer-to-peer communication and IPFS.
80, 443	TCP	For HTTP and HTTPS - serving APIs and hosted resources.
53, 953	TCP, UDP	For DNS resolution.

Before proceeding with the tau installation on the hosts, a few preliminary steps are required:

Ensure curl and vim (or your preferred text editor) are installed:

$ sudo apt update
$ sudo apt install curl vim

If you’re unfamiliar with vim, consider trying vim-adventures for a fun introduction.

To allow the seer protocol to operate correctly, DNS settings need adjustment:

$ sudo vim /etc/systemd/resolved.conf

In edit mode (:i), configure:

DNS=1.1.1.1
DNSStubListener=no

Then, apply the changes:

$ sudo systemctl restart systemd-resolved.service
$ sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf

Execute the following to install Docker:

$ curl -fsSL https://get.docker.com | sh

The initial host, in this scenario host-001-enterprise-starships-ws, will serve as the cornerstone for generating our network’s secrets.

The installation of the tau software is straightforward. Execute the command below:

$ curl https://get.tau.link/tau | sh

It’s worth noting that a single host can support multiple nodes, provided their ports do not overlap. However, for the purposes of this guide, we will maintain a one-node-per-host configuration.

Upon successful installation, you should see an output similar to the following:

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  3982  100  3982    0     0   3962      0  0:00:01  0:00:01 --:--:--  3966
Downloading release: v1.1.2
From: https://github.com/taubyte/tau/releases/download/v1.1.2/tau_1.1.2_linux_amd64.tar.gz
######################################################################## 100.0%
Installation complete

This signifies that tau has been successfully installed and is ready for configuration and use.

The configuration process for a node is straightforward and can be executed with a single command:

$ sudo tau config generate -n enterprise.starships.ws \
      -s compute --protos all --ip 34.133.173.124 \
      --dv --swarm 

Here’s a quick rundown of the options used:

• -n specifies the domain name (or network name) for the node.
• -s assigns a name to this configuration, often referred to as a “shape.”
• --protos all activates all available protocols.
• --ip indicates the IP address the node should use for announcements.
• --dv generates a domain validation key pair.
• --swarm creates a swarm key for network clustering.

Note: It’s generally not advisable to enable all protocols on a single node due to potential conflicts and resource constraints. This article simplifies the setup for demonstration purposes. Adjustments to the protocol configuration can easily be made with a single command, which we will explore in future discussions.

Upon successful configuration, you’ll receive the node’s ID as confirmation:

[INFO] ID: 12D3KooWKv5oNF2a6h9sYzRUPEAaYe6feTbBbcLYZYVFrMDDCHzY

With the basic configuration in place, some adjustments are necessary for optimal performance and alignment with your specific requirements:

$ sudo vi /tb/config/compute.yaml

For instance, you might want to update the generated domain to match your preferred domain. In this example, I’ll use e.ftll.ink:

generated: e.ftll.ink

Additionally, since the gateway and substrate protocols cannot coexist on the same node, we’ll remove the gateway protocol from our list. The revised configuration should look something like this:

privatekey: <redacted>
swarmkey: keys/swarm.key
protocols:
    - auth
    - patrick
    - monkey
    - tns
    - hoarder
    - substrate
    - seer
p2p-listen:
    - /ip4/0.0.0.0/tcp/4242
p2p-announce:
    - /ip4/34.133.173.124/tcp/4242
ports:
    main: 4242
    lite: 4247
    ipfs: 4252
location:
    lat: 40.076897
    long: -109.33771
network-fqdn: enterprise.starships.ws
domains:
    key:
        private: keys/dv_private.pem
        public: keys/dv_public.pem
    generated: e.ftll.ink
plugins: {}

Should the location be inaccurately determined, you have the option to correct it manually.

The final step involves validating the configuration to ensure its accuracy and completeness:

$ sudo tau conf validate -s compute

A lack of error messages signifies that your configuration is correct.

To initiate the node manually, execute the following command:

$ sudo tau start -s compute

Next, verify that your node is active and accessible. Open your web browser and navigate to slimdig.com. There, you’ll perform a simple check: (1) input seer.tau.<your domain>, (2) enter your server’s public IP, and (3) click on the A button.

Seeing your server’s IP address as a return verifies that your node is live and operational.

For a more resilient setup, converting the manually started service into a systemd service ensures that it will automatically restart upon failure or server reboot.

First, halt the currently running service by using CTRL-C. Then, proceed to create a systemd service file:

$ sudo vim /lib/systemd/system/tau@.service

Incorporate the following configuration into your systemd service file:

[Unit]
Description=Taubyte Tau Service Running %i

[Service]
Type=simple
ExecStart=/tb/bin/tau start -s %i
StandardOutput=journal
User=root
Group=root

LimitAS=infinity
LimitRSS=infinity
LimitCORE=infinity
LimitNOFILE=65536

Restart=always
RestartSec=1

[Install]
WantedBy=multi-user.target

After saving the file, enable and initiate the service to ensure it starts automatically:

$ sudo systemctl enable tau@compute
$ sudo systemctl start tau@compute

To confirm the service is running as expected, check its status:

$ sudo systemctl status tau@compute

You should see output similar to the following, indicating that the tau@compute service is active and running:

● tau@compute.service - Taubyte Tau Service Running compute
     Loaded: loaded (/lib/systemd/system/tau@.service; enabled; vendor preset: enabled)

Feb 09 22:43:52 host-001-enterprise-starships-ws systemd[1]: Started Taubyte Tau Service Running compute.

This service configuration ensures your node remains operational across restarts and system updates, providing a stable and reliable infrastructure component.

The Seer protocol plays a crucial role in DNS load balancing within the Taubyte ecosystem, enabling protocol translation into valid IP addresses using the <protocol>.tau.<domain> convention. This powerful feature allows for efficient load balancing across a Taubyte-based cloud with just a simple CNAME (or ALIAS, for DNS providers that support it) record.

To leverage this capability, it’s necessary to delegate the tau subdomain to the nodes running the Seer protocol within your cloud. Here’s how you can do this with your DNS provider; the example below uses Namecheap for the domain starships.ws:

1. Adding the Node as an A Record:

   • Select the A record type.
   • Name it (in this case, seer.<domain>).
   • Enter the IP address of the node.
   • Confirm by validating the entry.

2. Delegating with an NS Record:

   • Choose the NS record type for delegation.
   • Label it tau.<domain>.
   • Set its value to your chosen name (e.g., seer.<domain>).
   • Validate the entry to complete the delegation.

To ensure the DNS configuration is effective, use a tool like slimdig:

• Enter <protocol>.tau.<domain> (for this demonstration, tns.tau.enterprise.starships.ws).
• Ensure the query is set to a public DNS server like 8.8.8.8.
• Click on the A button to perform the lookup.

Keep in mind, DNS propagation can delay the effectiveness of these new entries, requiring multiple attempts over several minutes to verify.

Congratulations, your cloud is now operational! You can connect to it via tau-cli or the Web Console to deploy frontend interfaces, serverless computing functions, and more. The next steps will involve bringing the remaining two servers online to enhance our cloud’s resilience and capacity.

To efficiently replicate our initial setup across two additional hosts, we’ll first create a configuration template. This approach ensures consistency, particularly concerning the swarm key and domain validation keys.

Initiate the export with the following command, which will encrypt the secrets for added security:

$ sudo tau config export -s compute --protect

You’ll be prompted to enter a password for the encryption:

Password?

Remember this password; it’s crucial for the subsequent steps.

The exported configuration will resemble the following (omit the location to let it be automatically determined for the other nodes):

origin:
  shape: compute
  host: host-001-enterprise-starships-ws
  time: 2024-02-12T05:41:25.218338331Z
  protected: true
source:
  swarmkey: PZuGcV96BbfM...2RE8ZEfR2pZoM29z8
  protocols:
  - auth
  - patrick
  - monkey
  - tns
  - hoarder
  - substrate
  - seer
  p2p-listen:
  - /ip4/0.0.0.0/tcp/4242
  p2p-announce:
  - /ip4/34.133.173.124/tcp/4242
  ports:
    main: 4242
    lite: 4247
    ipfs: 4252
  network-fqdn: enterprise.starships.ws
  domains:
    key:
      private: BDN9SEUFsolg...25pUUrUpFxSFhjlCv
      public: cmS5kmov/cJ9...NezzWwcYVj4YVNOg
    generated: e.ftll.ink
  plugins: {}

To facilitate the bootstrap process for the additional nodes, retrieve the first node’s multi-address:

$ sudo tau config show -s compute | grep Announce

The output should provide the address necessary for peer connections:

│ P2PAnnounce │ /ip4/34.133.173.124/tcp/4242/p2p/12D3KooWKv5oNF2a6h9sYzRUPEAaYe6feTbBbcLYZYVFrMDDCHzY │

In this case, the multi-address is:

/ip4/34.133.173.124/tcp/4242/p2p/12D3KooWKv5oNF2a6h9sYzRUPEAaYe6feTbBbcLYZYVFrMDDCHzY

Establish SSH connections to the remaining two hosts, ensuring they are prepared as described in the Preparing the Hosts section. Transfer the compute.tmpl.yaml template (minus the location) and the systemd service file to each.

On each of the new hosts, install tau using the same command as before:

$ curl https://get.tau.link/tau | sh

This step lays the foundation for a streamlined expansion of your Taubyte cloud, leveraging the power of configuration templates and ensuring a uniform setup across your infrastructure.

With the template and necessary preparations in place, proceed to configure the additional hosts:

• For the Second Host:

  $ sudo tau config gen --ip 34.130.131.76 --use compute.tmpl.yaml  --bootstrap /ip4/34.133.173.124/tcp/4242/p2p/12D3KooWKv5oNF2a6h9sYzRUPEAaYe6feTbBbcLYZYVFrMDDCHzY
  

• For the Third Host:

  $ sudo tau config gen --ip 35.235.122.141 --use compute.tmpl.yaml  --bootstrap /ip4/34.133.173.124/tcp/4242/p2p/12D3KooWKv5oNF2a6h9sYzRUPEAaYe6feTbBbcLYZYVFrMDDCHzY
  

Important considerations:

• Utilize the correct IP addresses for each host.
• The template’s encryption password will be required.
• Each host is bootstrapped to the initial node, ensuring connectivity and synchronization within the network.

After configuration, ensure the tau service will automatically start on each host:

$ sudo cp ~/tau@.service /lib/systemd/system/tau@.service
$ sudo systemctl enable tau@compute
$ sudo systemctl start tau@compute

Verify the service status to confirm active running:

$ sudo systemctl status tau@compute

To ensure all nodes are correctly registered and operational, utilize DNS queries:

1. Enter <protocol>.tau.<domain> and select A to perform the query.

You should observe all three servers listed, indicating successful network integration.

With the cloud infrastructure now horizontally expanded and operational, attention turns to ensuring seamless interaction among all hosts and leveraging their capabilities for DNS load balancing.

• For the Main Domain: Additional A records for each new host need to be added to the DNS configuration.

Running a DNS lookup should now reflect all active hosts:

• For the Generated Domain: Delegate the specified subdomain to your cloud by adding the appropriate NS entry, enhancing domain management and flexibility.

Ensure all nodes are aware of each other to facilitate network resilience and data consistency:

1. Collect and share the multi-addresses among all nodes.
2. Update the peers section in each node’s configuration to include all peers.
3. Validate the configuration for accuracy.

No restart is required as peers are dynamically managed, but ensuring accurate configuration enhances the network’s ability to recover and scale effectively.

To extend our cloud’s reach, we proceed to configure the additional nodes with precision, ensuring a seamless integration into our existing setup. Execute the following commands on the designated hosts to generate their configurations, employing the compute.tmpl.yaml as a blueprint and leveraging the bootstrap mechanism for network connectivity:

• On the Second Host:

  $ sudo tau config gen --ip 34.130.131.76 --use compute.tmpl.yaml  --bootstrap /ip4/34.133.173.124/tcp/4242/p2p/12D3KooWKv5oNF2a6h9sYzRUPEAaYe6feTbBbcLYZYVFrMDDCHzY
  

  [INFO]  ID: 12D3KooWSJZQAPtVaLuusfr3g71FZEeyxr8HdmPcjKeQonHmQXn2
  

• On the Third Host:

  $ sudo tau config gen --ip 35.235.122.141 --use compute.tmpl.yaml  --bootstrap /ip4/34.133.173.124/tcp/4242/p2p/12D3KooWKv5oNF2a6h9sYzRUPEAaYe6feTbBbcLYZYVFrMDDCHzY
  

Important: Use the correct IP addresses for each host and the first node’s multi-address for initial discovery. You’ll be prompted to enter the password established during the template creation phase—this step is crucial for maintaining security and consistency across your cloud infrastructure.

To ensure our nodes remain resilient and automatically recover from reboots or unforeseen downtime, we embrace systemd’s robustness. On both nodes, execute the following:

$ sudo cp ~/tau@.service /lib/systemd/system/tau@.service
$ sudo systemctl enable tau@compute
$ sudo systemctl start tau@compute

Verify the service’s heartbeat:

$ sudo systemctl status tau@compute

A litmus test for operational integrity, DNS queries reveal the network’s pulse. Employ <protocol>.tau.<domain> and observe:

The triad of servers, now visible, confirms our cloud’s expanded horizon.

With our cloud now stretching across horizons, it’s paramount to ensure inter-node discovery and dynamic load balancing. Our next steps solidify the network’s backbone, priming it for seamless scalability.

Augmenting our DNS configuration to include all nodes under seer.<domain> enriches our network’s resilience:

A subsequent dig command unfurls the network’s canvas, displaying our nodes in unison:

For those wielding Linux, dig a seer.enterprise.starships.ws +noall +answer yields an ensemble of IPs, signifying our united front.

Recall our s.ftll.ink domain, a digital expanse awaiting its purpose. An NS entry, pointing to our cloud, bestows it with life:

In the realm of distributed systems, autonomy is king. Ensuring each node can independently find its brethren guarantees our network’s resilience. With the multi-addresses of all nodes now known, we weave them into each node’s fabric:

peers:
  - /ip4/34.133.173.124/tcp/4242/p2p/12D3KooWKv5oNF2a6h9sYzRUPEAaYe6feTbBbcLYZYVFrMDDCHzY
  - /ip4/34.130.131.76/tcp/4242/p2p/12D3KooWHrp2t9npN2TW4dv47uEvJh6qfs6U2ymhkiVVNpcR3cWE
  - /ip4/35.235.122.141/tcp/4242/p2p/12D3KooWKQJfLU74VJzsvhAKUJ8KQidBr1CowMo1e1YRrSb2v

TZd

A final validation ensures our network’s readiness to face the digital expanse:

$ sudo tau config check -s compute

No error messages? Then stand back and behold—a cloud, not just built, but crafted, ready to rival the titans.

No need for manual restarts. The peer connections are maintained in a persistent database, ensuring that even after recovery or reconfiguration, the nodes automatically recognize each other without intervention.

Congratulations, your very own cloud infrastructure is now operational, poised to compete with giants like Cloudflare, Netlify, Vercel, and Fastly. Let’s walk through a hands-on tour to see it in action.
