Mobile Backend as a Service
without MBaaS • need own server, database,
services • time/costs/devs to setup • flexible server configuration
Backend without code. parse.com: myth vs reality. Stanfy MadCode Meetup, stanfy.com, 08.04.2015
with MBaaS • ready to start • no need of server developers* • dependent on MBaaS
configuration
our backgroundsocial network
• facebook login • likes, shares, comments • complicated relations between users
yet another social network • many pictures • anonymous users • lots of push notifications (incl geo-based) • moderation • complicated business logic (smart feed)
personal dairy • many photos • offline mode with synchronization
medication alarm • push notifications • offline mode • customizations ‘on the fly’ • client-friendly users’ statistics
Backend without code. parse.com: myth vs reality. Stanfy MadCode Meetup, stanfy.com, 08.04.2015
why would I use Parse?
• cross platform • easy setup • proof of concept / mvp • push notifications • cost saving* • cloud code
disclaimer: i don’t work for parse.com
Backend without code. parse.com: myth vs reality. Stanfy MadCode Meetup, stanfy.com, 08.04.2015
be careful if
• huge application (many objects) • million of users • streaming • chatting

security
questionable
Backend without code. parse.com: myth vs reality. Stanfy MadCode Meetup, stanfy.com, 08.04.2015
security
• application keys are public • easy to find keys and connect to db • easy to generate spam requests
• turn off the “Allow client class creation” • set the correct ACL permissions
• do not allow read/edit data to non-authorized users
Backend without code. parse.com: myth vs reality. Stanfy MadCode Meetup, stanfy.com, 08.04.2015
easy setup
• create Parse application • download SDK • write code • write+deploy cloud code*
Backend without code. parse.com: myth vs reality. Stanfy MadCode Meetup, stanfy.com, 08.04.2015
client (iOS) SDK
• cocoapods • “saveEventually” • cache • inner storage • working with files (PFFile) • in-app purchases support • ready UI interfaces • weird crashes —>
Backend without code. parse.com: myth vs reality. Stanfy MadCode Meetup, stanfy.com, 08.04.2015
saving pictures from phone
• restrictions: 10MB per file • native support of uploading, downloading, progress (PFFile) • long upload* • Amazon S3 as alternative
Backend without code. parse.com: myth vs reality. Stanfy MadCode Meetup, stanfy.com, 08.04.2015
cloud code: awesomeness
• mongoDB • REST API • javascript + python • better to do everything on cloud • debug mode: “parse develop AppName” • cloud modules (email sending)
Backend without code. parse.com: myth vs reality. Stanfy MadCode Meetup, stanfy.com, 08.04.2015
cloud code: awesomeness (2)
• triggers (beforeSave, afterSave) • join queries • background jobs • Parse.Promises (a-la semaphores) • paging support (limit, offset)
Backend without code. parse.com: myth vs reality. Stanfy MadCode Meetup, stanfy.com, 08.04.2015
cloud code: pain• async (“callback hell”) • debugging:
• change CC -> deploy -> check -> change • logs only
• short execution time • 15/3 sec for function/trigger • 15 min for job
• application keys in global.json file
Backend without code. parse.com: myth vs reality. Stanfy MadCode Meetup, stanfy.com, 08.04.2015
cloud code: pain (2)
• inner queries • 1000 objects limit per query • limited ‘count’ operation
Backend without code. parse.com: myth vs reality. Stanfy MadCode Meetup, stanfy.com, 08.04.2015
dev and prod apps
• create dev app in Parse • develop-develop-develop • master build points on dev app
• iOS keys • javascript keys
• use ‘parse develop AppName’ to debug CC
• create/clone prod app in Parse • deploy CC • appstore build points on prod app
• iOS keys • javascript keys
Backend without code. parse.com: myth vs reality. Stanfy MadCode Meetup, stanfy.com, 08.04.2015
dev and prod apps
separate applications on Parse
different keys inside iOS

to migrate from Parse
• update client applications (iOS) • one click export -> json files
Backend without code. parse.com: myth vs reality. Stanfy MadCode Meetup, stanfy.com, 08.04.2015
benefits
from dev perspective • easy to integrate, easy to use • cool client SDK • awesome* documentation and forum • push notifications (fast and easy setup) • cloud code awesomeness
Backend without code. parse.com: myth vs reality. Stanfy MadCode Meetup, stanfy.com, 08.04.2015
benefits
from customer/manager perspective • reduce time to market • reduce development/support cost* • various analytics (users, events, crashes..) • various services out of the box (email confirmation, sending emails..) • flexible pricing • user-friendly admin db
Backend without code. parse.com: myth vs reality. Stanfy MadCode Meetup, stanfy.com, 08.04.2015
disadvantages
from developer perspective • request-driven development (limits) • not developer-friendly admin site (can’t drop class programmatically) • no autobackups for free plan • cloud code pain
Backend without code. parse.com: myth vs reality. Stanfy MadCode Meetup, stanfy.com, 08.04.2015
disadvantages
from client/manager perspective • dependence on 3rd-party servers
• long-term strategy risks (“what if Parse will be shut tomorrow?”) • performance issues* • not flexible for business (“we can’t implement this!”)
• limited build-in set of tools • cost*
• hard to foresee spendings
