Tomo Deployment Tool

Deploying Rails using Tomo

Heroku Reviews - June 22, 22

 

WHAT

Deploy full stack apps (FE + BE + DB)

Deploy full stack apps without the need of all the technical skills needed for AWS

Prototyping - quick deployment

Build an entire pipeline (dev, test and prod)

Ship web apps without a lot of effort

Build app very quickly

Build, deploy and run your app very easily

Very helpful to build highly large data apps

Easy to deploy full stack applications fast without worrying about configuring

HOW

Connect your app using a Git repo and it will handle the deployment

USE

Simple and intuitive interface

Simple and easy to use, even for users with minimal knowledge of application architecture

EASY

Easy to setup

You can set up an entire environment very fast

DEPLOYMENT SPEED

Instant deployment

One-step deployment process

Their auto-maintenance and auto-deploy services saves a lot of time and effort

DEPLOYMENT EASE

Makes it easy to deploy apps without having the knowledge of managing a server

CLI tool - easy to deploy

Quick and easy deployment

INTEGRATIONS

Seamless integration with Git

Ease with which we can deliver updated code and new features

Add ons

Marketplace

Easy installation of plugins and add-ons

Integrate third-party website with Salesforce

Connect database with a single click with the help of plug in

LEARNING CURVE

Less to learn for developers

COMPLEXITY

Complexity < (AWS or GCP)

SCALING

Scales with you

Autoscale based on usage

Autoscale our platform

TOOLS

Migration tool

Powerful metrics to monitor the app

ZERO DOWNTIME

No downtime

Rolling restarts (to fix delays in requests during deploy)

Perform a rollback to a previous version with just one click

TIME SAVINGS

Saves a lot of time in creating and deploying new apps

COST SAVINGS

Streamline the process for developers and saves costs on app development

Reduced the dependence small teams have on Devops (saves costs)

DOCUMENTATION

for:

  using several environments

  tuning memory usage

  deploying from Dropbox

Detailed sample apps and code for starting a new app

SECURITY

Secure and protected ecosystem

Dev / Prod Environment Parity

Being able to switch from local to remote environment

You can work locally with remote database

WHO

Great for small teams and if you need to validate your product

Single developer or small teams can focus on the project and get it launched, without too much hassle

CONS

Once you get substantial traffic, you have to ask yourself whether your budget should focus on:

more dynos

code optimization

different platform

Support

Contract trap

License cose

Expensive

Gets expensive quickly

Non traditional server environment

Deploy fixed number of apps

Apps go to sleep if there is no user activity

Environment configuration setup is slightly complex (vs Netlify)

CI service is fairly limited (works fine with CircleCI & Travis)

Minimal language support

Low network performance

Upsell on features you may not need

To the uneducated, they will opt into unnecessary features that are otherwise free

Security add-ons like AWS would be nice

Need a separate service for repo like Github, rather than having everything inclusive

30 seconds restriction (not compatible with OS libraries)

Request gets stuck behind slow request

Hard to gauge the capacity needed

Hit by downtimes (not much to do once it goes down)

If AWS goes down Heroku will go down

SSH Basics

 We learned a little bit about the SSH protocol and how to use the ssh program to connect to a remote server.

SSH protocol was introduced for secure communication using the pub- lic key encryption on the network. OpenSSH is a collection of programs implementing this protocol and available to us.

Connecting to a remote server can be as easy as running ssh $USER@$HOST. In the case we create a server with password authentication, we can use ssh-copy-id to put the public key to the server and take advantage of SSH-keys only access.

We learned about SSH keys management. We can find our keys in ~/.ssh, generate new ones with ssh-keygen. We explored how ~/.ssh/authorized_keys is used for authorizing access using these keys and how SSH host keys are stored in ~/.ssh/known_hosts.

scp and sftp are the go-to tools for secure file transfer over SSH. Although using scp has some security implications given its original design, it’s safe to use in simple commands. rsync is another popular option.

Create a Node on VPS

1. Signup for VPS provider such as Linode
2. Create a node

Provisioning, Booting, Running

12 Factor App

 Heroku, with its 12-factor application model, has changed the way we think about building, deploying, and hosting web applications. 

The rise of containers, phoenix servers and continuous delivery has seen a move away from the usual approach to deploying web applications. Traditionally we have built an artifact and then installed that artifact into an application server. The result was long feedback loops for changes, increased build times and the not insignificant overhead of managing these application servers in production. Many of them are a pain to automate too. Most teams we work with favor bundling an embedded http server within your web application. There are plenty of options available: Jetty, SimpleWeb, Webbit and Owin Self-Host amongst others. Easier automation, easier deployment and a reduction in the amount of infrastructure you have to manage lead us to recommend embedded servers over application servers for future projects.

My notes

 

Secure Connection

1. Establish secure connection from the workstation to the servers.
2. Run deployment tasks
3. Upload configuration files
4. Log in
5. Put the public key on the server
6. Create a secure connection using the private key
7. Avoid password based authentication
8. Use SSH tunneling to reuse the connection for other services

SSH Keys

Setup passwordless login on the server

• Use ssh-keygen to make a new pair of SSH keys
• Create a virtual private server in the admin panel
• Copy the SSH keys using ssh-copy-id utility for providers that setup password-based authentication

Success Criteria

Login using SSH as root

ssh root@server-hostname-or-ip-address

Remote Shell

• Install ssh-agent on Mac OS
• Connect to server from the client, use ssh command
• Define USER environment variable to specify hte user on the host
• Define HOST environment variable to specify the remote server's hostname or IP address
• The default configuration file used is ~/.ssh/config
• The default identity file (private key) is ~/.ssh/id_rsa
• The identity_file, login_name and port values can be specified per host in the configuration file (~/.ssh/config)

File Transfers

Steps

1. Signup for hosting provider
2. Create a node
3. Provision a node
4. Deploy code
5. Maintain node

• Figure out which steps are done by the customer and which steps are done by the product.
• Establish secure
