Early 2015 11 inch MacBook Air - RAM & Processor upgrade - is it possible

Hi ,

I have a Mac Air 11 inch early 2015. may i know if i can upgrade the RAM and processor (i mean are there provisions and slots available) and also Storage (now i have SSD of 256 GB). Is it OK to do so and is there any disadvantage of doing so? (like overheating or noise or something else).

I purchased it for simple uses but now thinking of using it for programming (typically, say Java based apps and run Docker containers locally). As an alternate to buying a new MacBook, i wanted to know if existing one would help me achieve with upgrades of h/w.

This is my hardware overview:

Model Name: MacBook Air

  Model Identifier: MacBookAir7,1

  Processor Name: Intel Core i5

  Processor Speed: 1.6 GHz

  Number of Processors: 1

  Total Number of Cores: 2

  L2 Cache (per Core): 256 KB

  L3 Cache: 3 MB

  Hyper-Threading Technology: Enabled

  Memory: 4 GB.

Thanks!!
